Two balls of equal mass undergo head-on collision while each was moving with a speed of . If the coefficient of restitution is , the speed of each ball after impact will be
Step 1: Given data
Speed,
Coefficient of restitution is .
Step 2: To find
Speed of each ball after impact
Step 3: Calculate the speed of the ball
There is no external force acting, momentum will be conserved.
…(1)
Here, are velocity of balls before impact and are velocity of balls after impact. are mass of balls.
…(2)
Here is a coefficient of restitution.
After solving equations (1) and (2) get the values of speeds are
Hence, speed of balls are and .
