# Max Height Achieved by Ball in Physics Project

• Michael17
In summary, a senior physics class is conducting a research project on projectile motion and has created a launching device for a cricket ball. The ball is launched at ground level with an initial velocity of 28m/s at a 30-degree angle to the horizontal. The problem at hand is to determine the maximum height the ball reaches, assuming no air resistance and an acceleration due to gravity of 9.8m/s. Suggestions for solving the problem include using kinematics equations.

A senior physics class conducting a research project on projectile motion constructs a device that can launch a cricket ball. The launching device is designed so that the ball can be launched at ground level with an initial velocity of 28m/s at an angle of 30 degrees to the horizontal. What is the maximum height that is achieved by the ball, given that the acceleration due to gravity is 9.8m/s and there is no air resistance?

Any Ideas? Have you attempted the problem?

Witch kinematics equations do you think would be a good start?

## 1. What is the formula for calculating the maximum height achieved by a ball in a physics project?

The formula for calculating the maximum height achieved by a ball in a physics project is: h = (v2sin2θ)/2g, where h is the maximum height, v is the initial velocity of the ball, θ is the angle at which the ball is thrown, and g is the acceleration due to gravity.

## 2. How does the initial velocity of the ball affect the maximum height achieved?

The initial velocity of the ball directly affects the maximum height achieved. The higher the initial velocity, the higher the maximum height will be.

## 3. What is the role of angle in determining the maximum height achieved by a ball?

The angle at which the ball is thrown plays a significant role in determining the maximum height achieved. The maximum height will be achieved at an angle of 90 degrees (when the ball is thrown straight up) and will decrease as the angle decreases.

## 4. How does air resistance affect the maximum height achieved by a ball?

Air resistance can have a significant impact on the maximum height achieved by a ball. In the presence of air resistance, the ball will experience a downward force, causing it to travel a shorter distance and achieving a lower maximum height compared to when there is no air resistance.

## 5. Does the mass of the ball affect the maximum height achieved?

The mass of the ball does not affect the maximum height achieved. The maximum height is determined by the initial velocity and angle at which the ball is thrown, as well as the force of gravity and air resistance acting on the ball.
