A disc is rolling the velocity of its centre of mass is V_cm then which one will be correct :-
The velocity of highest point is 2V_cm and point of contact is zero
The velocity of highest point is V_cm and point of contact is V_cm
The velocity of highest point is 2V_cm and point of contact is V_cm
The velocity of highest point is 2V_cm and point of contact of contact is 2V_cm
Correct Answer
Detailed Explanation
For a rolling object, the velocity at the highest point is twice the velocity of the center of mass.
