A hockey ball of mass 200 g travelling at $10\ ms^{-1}$ is struck by a hockey stick so as to return it along its original path with a velocity of $5\ ms^{-1}$. Calculate the change of momentum which occurred in the motion of the hockey ball by the force applied by the hockey stick:
The change in momentum of a vehicle weighing 2000 kg when its speed increases from 36 km/h to 72 km/h uniformly is :
A molecule of mass $m$ of an ideal gas collides with the wall of the vessel with the velocity $v$ and returns back with the same velocity. The change in the linear momentum of the molecule will be:
A 4-kilograms ball slides over horizontal friction less surface with velocity of 1 meter per second ball strike the post and rebounds upward perpendicular to the initial direction with same speed.
Calculate the change of momentum of the ball in initial direction.
A cricket ball of mass 500 g is moving with speed of $36 \,km\,h^{-1}$. It is reflected back with the same speed. What is the impulse applied on it?
A mass of 2 kg at rest travels for 4 seconds with an acceleration of 1.5 m $s^{-2}$. Find the gain of the momentum of the body.
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 in momentum of $0.4\, kg\, m\, s^{-1}$ in a body whose mass is 1 kg is:
The time, in which a force of 4 N produces a change in momentum of 0.4 kg m $s^{-1}$ in the body is:
