A hollow spherical shell has mass $8\mathrm{.}15$ kgkg and radius $0\mathrm{.}200$ mm$.$ It is initially at rest and then rotates about a stationary axis that lies along a diameter with a constant acceleration of $0\mathrm{.}875$ rad$/$s$2$rad$/$s$2.$

Part A

What is the kinetic energy of the shell after it has turned through $6\mathrm{.}25$ revrev?
