An object A of mass 2 kg is moving on a frictionless horizontal track has perfectly inelastic collision with another object B of mass 3 kg made of the same material and moving in front of A in same direction their common speed after the collision is 4 m//s Due to the collision the temperature of the two objects which was initially the same, is increased though only by 0.006^(@) C What was the initial speed (in m//s) of the colliding object A before the collision?

Collision is a physical process in which two or more objects, either particle masses or rigid bodies, experience very high force of interaction for a very small duration. It is not essential for the objects to physically touch each other for collision to occur. Irrespective of the nature of interactive force and the nature of colliding bodies, Newton's second law holds good on the system. Hence, momentum of the system before and after the collision remains conserved if no appreciable external force acts on the system during collision. The amount of energy loss during collision, if at all, is indeed dependent on the nature of colliding objects. The energy loss is observed to be maximum when objects stick together after collision. The terminology is to define collision as 'elastic' if no energy loss takes place and to define collision as 'plastic' for maximum energy loss. The behaviour of system after collision depends on the position of colliding objects as well. A unidirectional motion of colliding objects before collision can turn into two dimensional after collision if the line joining the centre of mass of the two colliding objects is not parallel to the direction of velocity of each particle before collision. Such type of collision is referred to as oblique collision which may be either two or three dimensional. For which of the following collisions, the external force acting on the system during collision is not appreciable as mentioned in paragraph 1.

A block B is at rest on the rough horizontal surface as shown. Another block A collides with B . Then, which of the following statement is correct? ( i ) Impulsive friction acts on block B . ( ii ) Conservation of momentum can not be applied on a system (A+B) along x-"axis" for the situation just before and just after the collision. ( iii ) Conservation of momentum can be applied on system (A+B) along x-"axis" for the situation just before and just after the collision. ( iv ) Block A always moves along positive x-"axis" after collision.

Sphere of mass M and radius R is kept on a rough horizontal floor. A small particle of mass m, moving horizontally with velocity, collides with the sphere and sticks to it. Line of motion of particle before collision is at a heighth above the floor. Assume that mase of sphere is very large in comparison to particle so that we may assume that centre of mass of the combined system remains at the centre of the sphere after the collision. What will be the approximate velocity of combined system after the collision?
