Question

A spherical shell of mass M and radius R rolls with slipping down an

incline of length D. I_cm = 2/3MR². When the shell reaches the

bottom, find

a) the translational kinetic energy of the shell.

b) the rotational kinetic energy of the shell.

c) the amount of energy converted into heat by friction.

Answer 1

Hello Hasan

We need Angle of incline for calculations

For GPE slope is required

KE ( Translational ) = 1/2mv²

KE ( rotaional ) = 1/2 Iw²

MgH = KE1 + KE2 + loss

Where H = height of incline
