Where would this basketball tossed upward have the least amount of kinetic energy?
Open in App
Solution
The correct option is A Point X
As the ball is thrown up, its kinetic Energy is maximum.
As it moves upwards, the kinetic energy decreases and the potential energy increases.
At maximum height, the potential energy is maximum and the kinetic energy is minimum.
Upon descending from the maximum height, the kinetic energy increases and simultaneously, the potential energy decreases with height. Hence, at X, kinetic energy is minimum.
