A mass m of radius r is rolling horizontally without any slip with a linear speed v . It then rolls up to a height given by 3 4 v^2 g

Options

  1. Athe body is identified to be a disc or a solid cylinder
  2. Bthe body is a solid sphere
  3. CMOI of the body about instantaneous axis of rotation is 3 2 m r^2
  4. DMOI of the body about instantaneous axis of rotation is 2 5 m r^2

Correct answer

C. MOI of the body about instantaneous axis of rotation is 3 2 m r^2

Step-by-step solution

Use v= 2 g h where, =1+ l Mr ^2
