The two masses on the right are slightly spearated and initially at rest, the left mass in incident with speed `v_(o)`Assuming head on elestic collisions, (a)if `Mltm,` show that there are exactly two collisions and find all final velocities, if `Mgtm` show that there are three collisions and find all final velocities.

Two bodies 1 and 2 of masses m and M are kept slightly separated . A third body 3 of mass m coming from left with velocity v makes a head- on elastic collision with m . Show that if m ge M there are exactly two collisions and find all final velocities and if m le M there are three collisions and find all final velocities .

A body of mass m makes an elastic collision with another identical body at rest. Show that if the collisionis not head on the bodiese to at right to each other after the collision.

A ball of mass m moving with velocity V , makes a head on elastic collision with a ball of the same moving with velocity 2 V towards it. Taking direction of V as positive velocities of the two balls after collision are.

A body of mass m is at rest. Another body of same mass moving with velocity V makes head on elastic collision with the first body. After collision the first body starts to move with velocity

Show that the two bodies of same masses exchange their velocities after an elastic head on collision .

A particle of mass m moving with velocity vecV makes a head on elastic collision with another particle of same mass initially at rest. The velocity of the first particle after the collision will be
