Question

Two objects of masses 100 g and 200 g are moving along the sameline and direction with velocities of 2ms^-1 and 1ms^-1 respectively. They collide and after the collision, the first object moves at a velocity of 1.67ms^-1. Determine the velocity of the second object.

Answer 1

Before collision

After collision
m₁ = 100 g = 0.1 Kg
m₂ = 200 g = 0.2 Kg
V₁ = 1.67 ms^-1
Let velocity of second object after collision is v₂ms^-1 Since there is no external force on the system.
