MHT CET · Physics · Center of Mass Momentum and Collision
An object of mass ' \(m\) ' moving with velocity ' \(u\) ' collides with another stationary object of mass ' M ' and stops just after the collision. The coefficient of restitution is
- A \(\frac{\mathrm{m}}{\mathrm{M}+\mathrm{m}}\)
- B \(\frac{M-m}{M+m}\)
- C \(\frac{\mathrm{m}}{\mathrm{M}}\)
- D 1
Answer & Solution
Correct Answer
(C) \(\frac{\mathrm{m}}{\mathrm{M}}\)
Step-by-step Solution
Detailed explanation
\(m u + M (0) = m (0) + M v_2\) \(v_2 = \frac{mu}{M}\)
