The coefficient of restitution e for a perfectly elastic collision is
Text Solution
Verified by ExpertsThe correct answer is:
A
: Coefficient of restitution or resilience of two bodies is defined as the constant ratio of relative velocity after impact to the relative velocity of the bodies before impact when the two bodies collide head on. Their velocities are in the opposite directions.
Thus 
constant 
The constant e is known as coeff. of restitution or resilience of two bodies. For a perfectly elastic collision, 
and for a perfectly inelastic collision, 
. Thus
