Questions & Answers

Q: What are the key variables involved in calculating the final height of the ball?

The key variables are initial velocity, acceleration due to gravity, final velocity, and the change in position (final height).

Q: Why is the final velocity of the ball considered to be zero at the peak of its trajectory?

The final velocity is zero at the peak because the ball momentarily stops before starting to descend due to gravity.

Q: How is the kinematic equation with four variables chosen to calculate the final height?

The kinematic equation with final velocity squared, initial velocity squared, acceleration, and change in position is used, as it includes the known variables and the unknown change in position.

Q: How is the final height of the ball calculated using the kinematic equation?

By plugging in the known values of initial velocity and acceleration, the change in position is determined and added to the initial height, resulting in the final height of the ball.
