A molecules in a gas container hits the wall with speed 200m`//`s at an angle `30^(@)` with the normal, and reboudns with the same speed. Is momentum conserved in the collision ? Is the collision elastic or inelastic ?

A and B are two identical balls. A moving with a speed of 6m//s , along the positive X-axis, undergoes a collision with B initially at rest. After collision, each ball moves along directions making angles of +-30^(@) with the X-axis. What are the speeds of A and B after the collision ? I s this collision perfectly eleastic ?

A body of mass m hits a wall with speed v at an angle of 30degree with normal and reflects at same angle from normal on other side of normal. The magnitude of change in linear momentum of the body is (Consider elastic collision)

If gas molecules undergo, inelastic collision with the walls of the container

A ball of mass 'm' moves normal to a wall with a velocity 'u' and rebounde with the same speed. The change in momentum of the ball during the rebounding is

A ball of mass 3 kg collides with a wall with velocity 10 m/sec at an angle of 30° and after collision reflects at the same angle with the same speed. The change in momentum of ball in MKS unit is-

Molecule of a gas in a container hits one wall (1) normally and rebounds back. It suffers number of collision and hits the opposite wall (2) which is at angle of 30^(@) with wall 1. Assuming the collision to be elastic and the small collision time to be the same for both the walls. The magnitude of average force by walls and 2 are F_(1) and F_(2) provide to molecule during collision satisfy

A particle of mass m strikes a disc of radius R and mass m with a speed u as shown in the figure. What is the speed of the particle just after the collision if the collision is perfectly inelastic ?
