Line Of Impact

A : During collision between two objects, the momentum of colliding objects is conserved only in direction perpendicular to line of impact. R : The force on colliding objects in direction perpendicular to line of impact is zero.

Statement-1 : In a perfectly inelastic collision between two spheres, velocity of both spheres just after the collision are not always equal. Statement-2 : For two spheres undergoing collision, component of velocities of both spheres along line of impact just after the collision will be equal if the collision is perfectly inelastic. The component of velocity of each sphere perpendicular to line of impact remains unchanged due to the impact.

consider collision between a block A and a ball B. the block is constrained to move along a horizontal surface. Ignore friction at any of the surfaces. Impulsive. Force between block and ball is along the line of impact and the impulse of reaction exerted by ground is in vertical direction , which is an external force on the system.

A sphere of mass m falls on a smooth hemisphere of mass M resting with its plane face on smooth horizontal table, so that at the moment of impact, line joining the centres makes an angle with the vertical. The velocity of sphere just before impact is u and e is the coefficient of restitution.
