Question

The moment of inertia of a solid cylinder about
its axis is I. It is allowed to roll on a surface
without slipping. If its angular velocity is w,
then its K.E. is:
a) 1/2Iw^2
b) Iw^2
c) 3/2Iw^2
d) 2Iw^2

Answer 1

Answer:

interia is the tendency of a body to remain at rest to I. uniform motion. when acted onby an external force

so it's kinetic energy shall be a
