Olympiad workbookNSEPCenter of Mass, Momentum and Collision
Two small masses m and M lie on a large horizontal frictionless circular track of radius R . The two masses are free to slide on the track but constrained to move along a circle. Initially the two masses are tied by a thread with a compressed spring between them (spring of negligible length being attached with none of the two masses). The compressed spring stores a potential energy U ₀ . At a certain time t =0 the th
Options
- AThe angle turned by mass m before the collision is =4 3
- BThe velocity of mass m on the track is u= 4 U₀ 3 m
- CThe time taken to collide for the first time is t₁=2 R m 3 U₀
- DThe time taken for the second collision is t₂=2 R 2 m 3 U₀
Correct answer
