Question

In perfectly inelastic collisions, the relative velocity of the bodies: (A) before impact it zero (B) before impact is equal to that after impact (C) after impact is zero (D) is characterized by none of the above

As in a perfectly inelastic collision, two bodies stick together after the collision and move with same velocity, so their relative velocity after the impact is zero.

Q. In perfectly inelastic collisions, the relative velocity of the bodies:

before impact it zero

before impact is equal to that after impact

after impact is zero

is characterized by none of the above
