Question

Two objects of 100 gm and 209gm are moving along a same line and direction with velocities 2ms and 1ms. respectively. they collide after the collision, the first object moves at velocity 1.67ms. determine the velocity of the second object ​

Answer 1

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.
