An 0.145-kg baseball pitched horizontally at 35.0 m s strikes a bat and is popped straight up to a height of 55.6 m. If the contact time is 1.4 ms, calculate the average force on the ball during the contact.

By applying Newton's second law of motion the value of x component is 1 m/s^2 and the y component has the value of 0 m/s^2.

In contrast to the first law of motion, the second law of motion deals with the behaviour of objects when all external factors are in equilibrium.The second rule of motion, which is more quantitative, is frequently applied to determine what occurs when a force is present.
According to Newton's second rule, an object's acceleration is determined by its mass and the total force that is operating on it.The mass of the body has an inverse relationship with acceleration, which is exactly proportionate to the total force exerted on the body. This implies that as the force exerted on an object increases, so does the object's motion. Similar to how an object's motion decreases as its mass increases, so does its mass.
By applying Newton's second law of motion:-

for x component:

4N - 2N = 2a

2= 2a and a = 1 m/s^2.

for y component:

3N-(2N+1N)= 2a

a= 0m/s^2.

Answer:

I completely agree with the first person's response.

Explanation:

They deserve Brainliest. Have a great summer.

(a) Using conservation of energy, the velocity of the ball at the top of the ramp is 3.9 m/s.
(b) When the height of the ramp is 1 m, the ball does not make it to the top of the ramp

Given,

Height of the ramp, h = 0.75 m
Initial velocity of the center of mass, u = 4.2 m/s

(a) What is its velocity at the top of the ramp?

The bowling ball rolls up a ramp of height 0.75 m without slipping to storage, and it has an initial velocity of its center of mass of 4.2 m/s. It is asked to determine the velocity of the ball at the top of the ramp.
Let the velocity of the ball at the top of the ramp be v.
By the law of conservation of energy, the potential energy of the ball at the bottom of the ramp is equal to the kinetic energy of the ball at the top of the ramp.
PE at the bottom of the ramp = KE at the top of the ramp

mgh = (1/2)mu² + (1/2)Iω²

where
m = mass of the ball
g = acceleration due to gravity
I = moment of inertia of the ball
ω = angular velocity of the ball

Assuming the ball is a solid sphere,

I = (2/5)mr²

where r is the radius of the sphere
At the bottom of the ramp,
PE = mgh
At the top of the ramp,
KE = (1/2)mu² + (1/2)(2/5)mu²
Substituting the given values,
PE = mgh = 0.75mg
KE = (1/2)mu² + (1/2)(2/5)mu²
= (1/2)(7/5)mu²
= (7/10)mu²

At the top of the ramp,

PE = KE
0.75mg = (7/10)mu²
v = u * √(7/10)
= 4.2 * √(7/10)
≈ 3.9 m/s

Therefore, the velocity of the ball at the top of the ramp is approximately 3.9 m/s.

(b) If the ramp is 1 m high does it make it to the top?

When the height of the ramp is 1 m,
PE = mgh = 1mg
At the top of the ramp,
KE = (1/2)mu² + (1/2)(2/5)mu²
= (1/2)(7/5)mu²
= (7/10)mu²

At the top of the ramp,

PE = KE
1mg = (7/10)mu²
u² = (10/7)gh
v = u * √(7/10)
= √(10gh/7)
≈ 3.96 √h m/s

Therefore, when the height of the ramp is 1 m, the ball does not make it to the top of the ramp.

Using the law of conservation of energy, the velocity of the ball at the top of the ramp is found to be approximately 3.9 m/s. When the height of the ramp is increased to 1 m, the ball does not make it to the top of the ramp.

The collision, the momentum of the truck is 1710 kg * (-3.55 m/s) = -6061 kg·m/s

To solve this problem, we can apply the principle of conservation of momentum. Momentum is defined as the product of an object's mass and velocity. Initially, the momentum of the truck is given by 1710 kg * (-10.1 m/s) = -17331 kg·m/s (negative because it's moving west), while the momentum of the car is mass_car * (-15.5 m/s).

After the collision, the momentum of the truck is 1710 kg * (-3.55 m/s) = -6061 kg·m/s, and the momentum of the car is mass_car * (-22.6 m/s).

Using the conservation of momentum, we equate the initial total momentum to the final total momentum. Therefore, -17331 kg·m/s + mass_car * (-15.5 m/s) = -6061 kg·m/s + mass_car * (-22.6 m/s).

Simplifying this equation, we find mass_car = (6061 kg·m/s - 17331 kg·m/s) / (-22.6 m/s + 15.5 m/s) = 1080 kg. Therefore, the mass of the car is 1080 kg.

The monochromatic laser light passing through two small slits with large spacing produces a bright fringe at the midpoint on a distant screen due to constructive interference, which occurs when the light from one slit travels exactly one wavelength farther than the light from the other slit, and both light waves reach the midpoint in phase.

The phenomenon described in your question is known as interference. When a laser beam passes through two small slits that are very close to each other, the light waves interfere with each other and create a pattern of bright and dark fringes on a distant screen. The bright fringe that is centered at the midpoint is caused by constructive interference, where the crests of the waves from one slit coincide with the crests of the waves from the other slit. This occurs because the distance traveled by the light from one slit to the midpoint is exactly one wavelength longer than the distance traveled by the light from the other slit.
It's important to note that for this phenomenon to occur, the slit spacing must be large compared to the distance to the screen, and the laser light must be monochromatic (meaning it contains only one wavelength). Additionally, the light waves must travel the same distance from each slit to the midpoint. These conditions are necessary for the waves to interfere constructively and create a visible interference pattern on the screen.

Complete cancellation will occur for a path difference equal to an odd multiple of half the wavelength.

The phenomenon of cancellation occurs in wave interference when two waves with the same frequency and amplitude are out of phase by 180 degrees, meaning that the crests of one wave coincide with the troughs of the other wave.

The path difference between the two waves determines whether or not complete cancellation will occur. When the path difference is equal to an odd multiple of half the wavelength (λ/2, 3λ/2, 5λ/2, etc.), the waves will be out of phase by 180 degrees and complete cancellation will occur.

Mathematically, we can express this condition as:

path difference = (m + 1/2) λ

where;

For example, if the wavelength of the waves is 1 meter and the path difference is 1/2 meter (m = 0), the waves will be in phase and constructive interference will occur. However, if the path difference is 1 meter (m = 1), the waves will be out of phase by 180 degrees and complete cancellation will occur.

Motion at Constant Speed

An object is said to travel at constant speed if the ratio of the distance traveled by the time taken is constant.

This can be written as the formula below:

\(\displaystyle v=\frac{d}{t}\)

Where  

v = Speed of the object

d = Distance traveled

t = Time taken to travel d.

Andrew's dog run a distance of d=17 meters in a time of t=9 seconds, thus its speed was;

\(\displaystyle v=\frac{17}{9}\)

v = 1.89 m/s

Andrew's dog's speed was 1.89 m/s

In order to calculate the potential energy of an object, we can use the formula below:

Where PE is the potential energy (in Joules), m is the mass (in kg), g is the gravity acceleration (in m/s²) and h is the height (in meters).

Since mass times gravity is equal to the weight force, we can also write the formula as follows:

Where W is the weight force (in Newtons).

So the formula will be:
