Question

Two bodies of equal masses ( m) moving with equal speed ( V) in opposite directions
collide and stick to each other. The resultant velocity of the combination is (1)
(a) V (b) 2V
(c) -V (d) zero

Answer 1

Two bodies of equal masses ( m) moving with equal speed ( V) in opposite directions collide and stick to each other. The resultant velocity of the combination is zero.

So the correct option is d.

• When two bodies with equal mass and velocity moving in opposite direction to each other and collided then their linear momentum will be zero.
• To conserve linear momentum their resultant velocity will also zero.
