Question
A solid sphere is rolling on a frictionless surface, shown in figure with a translation velocity v m/s. If it is to climb the inclined surface then v should be :


Options
A.

B.

C.2 gh
D.

Solution
Applying law of conservation of energy for roting body,
MV2 +
Iω2 = mgh
MV2 +
mr2 ×
= mgh
= gh
gh ⇒ v2 = 
v
MV2 +
Iω2 = mgh
MV2 +
mr2 ×
= mgh
= gh
gh ⇒ v2 = 
v
