Question

A spool (initially at rest) is pulled on a smooth
horizontal surface by constant horizontal force F,
such that the spool comes into a state of
sustained rolling motion. Kinetic energy of the
spool, after centre of mass of the spool has moved
a distance d, is
(1) Fd
(2)Fdr1/r2
(3)Fd(r1+r2)/r2
(4) Fdr2/(r1 + r2)​
