If two bodies collide and one is initially at rest,
is it possible for any one to be at rest after collision?

If two bodies collide and one is initially at rest, is it possible for both to be at rest after collision?

Two identical ball bearing in contact with each other and resting on a frictionless table are hit head on by another ball bearing of the same mass moving initially with a speed V shown in the figure. If the collision is elastic, which of the folloiwng shown in the figure is a possible result after collision ?

A 100 quintal freight car running freely at 10 km h^(-1) collides with and is coupled to a 70 quintal car originally at rest.Find the speed with which the cars move after collision.

If a body is not at rest, the net external force acting on it cannot be zero. is it true or false?

A block of mass m moving at a speed v collides with another block of mass 2 m at rest.The lighter block comes to rest after the collision.Find the coefficient of restitution.

When two identical spheres collide obliquely with one of them initialyly at rest,then fly off making an angle theta .What is the value of angle theta if the collision is elastic?

Two identical ball bearings in contact with each other and resting on a frictionless table are hit head-on by another ball bearing of the same mass moving initially with a speed V. If the collision is elastic, which of the following (Fig. 6.14) is a possible result after collision ?
