A spherical ball of mass `M` moving with initial velocity `V` collides elastically with another ball of mass `M`, which is fixed at one end of `L` shaped rigid massless frame as shown in Fig. (a). The `L` shaped frame contains another mass `M` connected at the other end.

The angular speed of `L` frame immediately after collision

A

`(u)/(7L)`

B

`(4u)/(2L)`

C

`(u)/(3L)`

D

`(4u)/(7L)`

Text Solution

Verified by Experts

Use conservation of linear and angular momemtum along with conservation of kinetic energy. (elastic collision)
