A batsman hits back a ball straight in the direction of the bowler without changing its initial speed of $12 ms^{-1}$. If the mass of the ball is $0.15\ kg$, determine the change in momentum of the ball. (Assume linear motion of the ball)
A loaded transport truck with a mass of 38000 kg is travelling at 1.20 m/s. What will be the velocity of a 1400 kg car if it has the same momentum?
What is the momentum of an object of mass m, moving with a velocity v?
An example of a force applied in the direction of motion is:
A force of $10 N$ acts on a body of mass $20 kg$ for $10 s$ .Change in its momentum is:
The quantity that best represents the motion of a rigid body is
In which of the following cases the net force is not zero?
A ball of mass 'm' moves normal to a wall with a velocity 'u' and rebounds with the same speed. The change in momentum of the ball during the rebounding is
The momentum of a 10 kg body moving at 36 km/h is:
The velocity of a body of mass 20 kg increases to 400 kgm/s in 5s. If initial velocity was 10 m/s, what is the momentum before the force acts?
