List of top Physics Questions on Conservation Of Momentum

A bullet of 10 g mass is fired at a speed of 50 m/s by a gun of 2 kg mass. The recoil speed of the gun (in m/s) is
The tennis ball of mass 120 g moving with a velocity of 20 m/s towards gets by a rocket of velocity and the final speed becomes 30 m/s with direction reversed. If the time of contact is 0.01 s, what is the average force acting on the ball?
After a collision, two particles move together, then the collision is?
Water falls from 100 metre height. What will be temperature rise per kg of water due to fall?
\(g = 10 \, \text{m/s}^2\), specific heat of water = 4200 Joule/kg°C
A sphere of 150 kg is kept on frictionless surface. A bullet of 0.15 kg mass with velocity 200 m/sec strikes the sphere and stops. After collision the velocity of sphere will be
A bomb at rest explodes into three pieces of equal masses. If two pieces move perpendicular to each other, each with a speed \( v \), then the speed of the third piece is:
If the resultant of all external forces acting on a system of particles is zero, then from an inertial frame one can surely say that:
One object of mass 20 kg is moving with the speed of 10 m/s is west direct another object of mass 10 kg is moving with 15 m/s in north direction. Both collide and stick together choose the correct alternative
Rocket works on the principle of conservation of :
A nuclear of mass number A emits a particle speed of a particle is v then what is recoil speed of nuclease.
