Laws of Motion ...

The impulse of a body is equal to :

A car and a lorry are moving with same momentum, if same braking force is applied, then :

The average force necessary to stop a hammer with 25 N-s momentum in 0.05s expressed in N is :

If two balls each of mass 0.6 kg moving in opposite directions with speed of 4 m s$$^{-1}$$ collide and rebound with same speed, then the impulse imparted to each ball due to other is:

A force acts on a body of mass 3 kg such that its velocity changes from 4 m s$$^{-1}$$ to 10 m s$$^{-1}$$. The change in momentum of the body is :

The time, in which a force of 2 N produces a change as momentum of 0.4 kg m s$$^{-1}$$ in the body is :

A hammer of mass 5 kg moving with a speed of 2 m s$$^{-1}$$ strikes the head of a nail driving it 20 cm into the wall. Find the impulse.

A man getting down from a running bus falls forward :

How does the proper inflation of tyre save fuel?

....................... is a self adjusting force.
