Show that in one dimensional elastic collision of two particales of equal mass,the partical exchange velocities after collisions.

Show that in two demensional elastic I collision between two bodies of equal mass and one body initialy at rest, they move at an angle of frac(pi)(2) after collision.

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.

If one of the two colliding particles is initially at rest, is it possible for both of the particles to be a rest after collision?

Which of the following potential energy curves in Fig. 6.18 cannot possibly describe the elastic collision of two billiard balls? Here r is the distance between centres of the balls.

A mass m moving with a speed u collides on a similar stationary mass and sticks to it. What is the velocity after collision?

Show that the total linear momentum of a system of particles is equal to the product of the total mass of the system and the velocity of its centre of mass.

A steel ball of radius 2cm is initially at rest.It is stuck head on by another steel ball of radius 4cm moving with a velocity of 0.72ms^-1.Assuming that the collosion in completely inceelastic.Calculate the velocity of the balls after collision.

What is the form of momentum in two dimensional collision?

A partical of mass 4*10^-27 kg moving with velocity one m/seccolides with another similar partical at rest inelastically.If the partical after colision combine togather,Find the velocity of the combined mass.

in an inelastic collision of two bodies, the quantities which do not change after the collision are the total kinetic energy/total linear momentum/total energy of the system of two bodies.
