Question

For a perfectly inelastic collision where two bodies stick together, the coefficient of restitution e is equal to:
Options
A 1
B 0.5
C 0
Correct Answer
D Infinity
Correct Answer

Option C is the correct answer.

Detailed Explanation

If the bodies stick together after the collision, their relative velocity of separation is zero. Therefore, e = (velocity of separation) / (velocity of approach) = 0.

Hint

What is the speed of separation if two objects are stuck together?
