A metal ball of mass moving with a velocity of has a head on collision with a stationary ball of mass . If after the collision, the two balls move together, find the loss in kinetic energy due to collision.
Step 1: Given data
Mass
Mass
Velocity
Velocity
Step 2: Concept used
Law of conservation of momentum,
Step 3: Finding the loss in kinetic energy due to collision
Now,
(initial)
(Final)
Then,
Loss in
Hence, the loss in kinetic energy due to collision is .
