The co-efficient of restitution for a perfectly elastic collision is:
Open in App
Solution
The correct option is A 1
The coefficient of restitution is defined as the ratio of the relative velocity of separation to that of approach, in a situation of two objects colliding with each other. The relative velocity of approach is the difference between the individual velocities of the two bodies before the collision.The relative velocity of separation is that after the collision.
In a perfectly elastic collision, the two relative velocities are exactly equal. Hence the coefficient becomes =1
