A body of mass 100 gm moving with an initial velocity of 4ms^(-1) collides with another body of mass 150 gm moving in opposite direction with velocity 6ms^(-1). If the collision is perfectly inelastic, then after the collision,

Answer»

The TWO bodies INTER change their velocities
The two bodies combine and move with a common VELOCITY of `2ms^(-1)` in the initial DIRECTION LIGHTER body
The two bodies combine and move with a common velocity of `5.2 ms^(-1)` in the initial direction of heavier body
The two bodies combine and move with a common velocity of `2ms^(-1)` in the initial direction of heavier body
