An object of mass 100 kg is accelerated uniformly from a velocity of 5 ms–1 to 8 ms–1 in 6 s. Calculate the initial and final momentum of the object. Also find, the magnitude of the force exerted on the object.

A hockey ball of mass 200 g travelling at 10 ms–1. It struck by a hockey stick so as to return. It along it's original path with a velocity at 5 ms–1. Calculate the change of momentum occurred in the motion of the hockey ball by the force applied by the hockey stick.

According to the third law of motion when we push on an object, the object pushes back on us with an equal and opposite force. If the object is a massive truck parked along the roadside. It will probably not move, A student justifies this by answering that two opposite and equal forces cancel each other comment on this logic and explain why the truck does not move.

Using a horizontal force of 200 N, we intend to move a wooden cabinet across a floor at a constant velocity. What is the friction force that will be exerted on the cabinet?

What is the momentum of an object of mass m, moving with a velocity v ?(a) (mv)2 (b) mv2 (c) 1/2 mv2 (d) mv
