A particle of mass m and veocity `vec(v)` collides elastically with a stationary particle of mass m Calculate the angle between velocity vector of the two partiicless after the 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

A particle of mass m moving with velocity u collides elastically with a particle of mass 3m at rest. After collision the heavier particle moves with velocity.

A particle of mass m_1 collides elastically with a stationary particle of mass m_2(m_1gtm_2) . Find the maximum angle through which the striking particle may deviate as a result of the collision.

A particle of mass m moving with speed V collides elastically with another particle of mass 2m. Find speed of smaller mass after head on collision

A particle of mass m collides with another stationary particle of mass M such that the second particle starts moving and the first particle stops just after the collision. Then which of the following conditions must always be valid ?
