Question

A ball of mass 0.2 kb is thrown vertically up wands by applying a force by hand. If the hand moves 0.2 m while applying the force and the ball goes up to 2m height further, find the magnitude of the force. (Consider g=10ms-2 )

  1. 16 N
  2. 20 N
  3. 22 N
  4. 4 N

The correct answer is: 22 N
