Question
For a perfectly inelastic collision where two bodies stick together, the coefficient of restitution e is equal to:
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?
