Passage

Read the passage given below and answer the questions that follow:

A small particle of mass m/10 is moving horizontally at a height of 3R/2 from ground with velocity 10 m/s. A perfectly inelastic collision occurs at point P of sphere of mass m placed on smooth horizontal surface. The radius of sphere is R, (m = 10 kg and R = 0.1 m) (Assume all surfaces to be smooth).
