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 6 ms^(-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 `2 ms^(-1)` in the INITIAL direction of 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 wo bodies combine and move with a common velocity of `2ms^(-1)` in the initial direction of heavier body
