Rotational MotionHard
Question
A solid sphere is placed on a horizontal plane. A horizontal impulse I is applied at a distance h above the central line as shown in the figure. Soon after giving the impulse the sphere starts rolling. The ratio h/R would be-


Options
A.
B.
C.
D.
Solution
Let the linear velocity of sphere be v ∴ I = mv
For angular momentum J = Iω
mv × h =
For angular momentum J = Iω
mv × h =
