NTA Abhyas JEE Main2020PhysicsWork, Power and EnergyPractice
A rubber ball is dropped from a height of 5 m on a plane. It bounces back to a height of 1 . 8 m . Find the coefficient of the restitution for the collision.
Correct answer
0.6
Step-by-step solution
If the ball is dropped from height h and bounces back to height h 1 h 1 = e 2 h ⇒ e = h 1 h = 1 . 8 5 = 0 . 6
