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

Options

A. the two bodies inter change their velocities
B. the two bodies combine and move with a common velocity of `2ms^(-1)` in the initial direction of lighter body
C. the two bodies combine and move with a common velocity of `5.2 ms^(-1)` in the initial direction of heavier body
D. the two bodies combine and move with a common velocity of `2ms^(-1)` in the initial direction of heavier body

Answer

D
