Question

d cylinder of mass 10kg rotates about its axis with angular speed
100 rad S
-1
. The radius of the cylinder is 0.25m. (i) What is the kinetic energy associated with the rotation of the
cyllinder?
(ii) What is the magnitude of angular momentum of the cylinder about
its axis.

Answer 1

\[I=m*r ^{2}\]
\[KE=\frac{ 1 }{ 2 }I*\omega ^{2}\]
\[L=r \times mv\] where L, r, and v are vector quantities.
