A ball moving with a speed of 9m.s strikes an identical ball at rest, such that direction fo eahc ball makes an angle 30^@ with the original line. Find the speed of two ball after collision.

A ball of mass m moving with a constant velocity strikes against a ball of same mass at rest.If e is the co-efficient if restitution what will be the ratio of velocity of two balls after collision?

Two billiard balls each of mass 0.05 kg moving in opposite directions with speed 6 m s~1 collide and rebound with the same speed. What is the impulse imparted to each ball due to the other?

The bQB A of a pendulum released from 30° to the vertical hits another bQB B of the same mass at rest on a table as shown in Fig. 6.15. How high does the bQB A rise after the collision? Neglect the size of the bQBs and assume the collision to be elastic.

Define the co-efficient of restitution. A particle of a mass m moving with a velocity u struck head-on against another particle of mass Km at rest.After collision the particles move with velocities V1 and V2 respectively.If the collision is prefectly elastic.Prove that the loss of kinetic energyof the particle with mass m is maximum when k=1.

Two objects, each of mass 1.5 kg, are moving in the same straight line but in opposite directions. The velocity of each object is 2.5 m s^-1 before the collision during which they stick together. What will be the velocity of the combined object after collision?

When is a collision said to be a perfectly inelastic? A mass is moving with speed v collides inelastically with another identical mass at rest. After collision, the first mass moves with velocity frac(nu)(sqrt 3) in a direction perpendicular to the initial direction of motion. Find the speed of the second mass after collision.
