Question

The diagram shows a hemispherical shell of mass m and radius R is hinged at point O placed on a horizontal surface.A ball of mass m strikes the shell at point $A$ (as shown in the figure) moving with velocity u inclined at an angle $θ = {tan}^{-1} (\frac{1}{2})$ and then it stops. For the given shell to reach horizontal surface OP what minimum speed u is required?

Options:

Answer:

D

Solution:

Torque about $O$ is zero as well angular momentum hence $ω = 0$

∴ Not possible
