SUMMARY
A tennis player tosses a tennis ball straight up and catches it after 2.00 seconds at the same height. The acceleration of the ball during flight is consistently -9.81 m/s², due to gravity. The velocity of the ball at its maximum height is 0 m/s, as it momentarily stops before descending. The initial velocity of the ball can be calculated using the formula v = v0 + at, yielding an initial velocity of 19.62 m/s, and the maximum height reached by the ball is 19.62 meters.
PREREQUISITES
- Understanding of kinematic equations in physics
