Question

derive an equation for Kinetic energy of the rolling body ?​

Answer 1

Answer:

Here is the solution buddy

Explanation:

The Energy stored in any object is the work done on the object by the force

Therefore Work done on moving body=Energy stored

Work done =Force*Displacement

Since F=m*a

And using third equation of motion---v^2/2a=s

Therefore KE=m*a*V^2/2a=1/2mv^2

Answer 2

Answer:

Total kinetic energy = translational kinetic energy + rotational kinetic energy. -Total kinetic energy = 12MV2+12Iω2. -ω=VR. -Total kinetic energy = 12MV2+12I(VR)2.
