A ball is thrown vertically upwards. Its velocity keeps on decreasing. What happens to its kinetic energy when its reaches the maximum height?
A stone is thrown vertically upwards with a velocity of 40 m/s. At what height will its kinetic energy and potential energy be equal?
A body of mass 2 kg is thrown upward with an energy 490 J. The height at which its kinetic energy would become half of its initial kinetic energy will be [g=9.8m/s2]
