A thin spherical shell lying on a rough horizontal surface is hit by a cue in such a way that line of action passes through the centre of the shell. As a result shell starts moving with a linear speed v without any initial angular velocity. Find the linear velocity to the shell when it starts pure rolling.

Text Solution
Verified by ExpertsThe correct answer is:
A
v f = v - 
……….. (i) F 1 r = α α
or F f r = 
or α α = 
or ω ω = 
t
or r ω ω = v f = 
t ………. (ii)
From eq. (i) and (ii) v f =
