The linear momentum of a ball of mass 50 g is 0.5 kg m s^-1. Find it's velocity.

A force of 15 N acts on a body of mass 2 kg. Calculate the acceleration produced.

Calculate the magnitude of force which when applied on a body of mass 0.5 kg produces an acceleration of 5 m s ^-2.

A force of 10 N acts on a body of mass 2 kg for 3 s, initially at rest. Calculate: (i) the velocity acquired by the body, and (ii) change in momentum of the body.
