Question

‘u₁’ and ‘u₂’ are the velocities of approach of two moving bodies in the same direction and their corresponding velocities of separation are ‘v₁’ and ‘v₂’. as per newton's law of collision of elastic bodies, the coefficient of restitution (e) is given by

Options:

A . e = v₁ - v₂/u₂ - u₁

B . e = u₂ - u₁/v₁ - v₂

C . e = v₂ - v₁/u₁ - u₂

D . e = v₁ - v₂/u₂ + u₁
