two objects of masses 100g and 200g are moving along the same line and direction with velocities of 2m/s and 1m/s respectively. they collide and after the collision , the first object moves at a velocity of 1.67m/s.determine the velocity of the second object.

Expert Answer:

Since no external force acts on them, the net change in momentum is zero.
Initial momentum = Final Momentum
(100 x 2) + (200 x 1) = (100 x 1.67) + (200 x V)
V = 1.165 m/s.
Hence the second object moves with 1.165 m/s in the same direction.
