After a totally inelastic collision, two objects of the same mass and same initial speeds are found to move together at half of their initial speeds. The angle between the initial velocities of the objects is

After a completely inelastic collision two objects of the same mass and same initial speed are found to move away together at half their initial speed. Find the angle between the initial velocities of the objects.

A ball of mass m moving with a velocity v undergoes an oblique elastic collision with another ball of the same mass m but at rest. After the collision if the two balls move with the same speeds , the angle between their directions of motion will be:

Two particles of equal masses moving with same momentum collide perfectly inelastically. After the collision the combined mass moves with half of the speed of the individual masses. The angle between the initial momenta of individual particle is

Two stones are projected simultaneously from a tower a differenct angles of projection with same speed 'u' . The distance between two stones is increasing at constant rate 'u' . Then the angle between the initial velocity vectors of the two stones is :

Consider the elastic collision f two bodies A and B of equal mass. Initially B is at rest and A moves with velocity v . After the collision -

A particle of mass m is projected from the ground with an initial speed u_0 at an angle alpha with the horizontal. At the highest point of its trajectory, it makes a completely inelastic collision with another identical particle, which was thrown vertically upward from the ground with the same initial speed u_0. The angle that the composite system makes with the horizontal immediately after the collision is

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?
