A spring ( ( k = 2 4 0 0 = 2 4 0 0

A spring $($k $=2400$ N$/$m$)$ is compressed $0\mathrm{.}2$ m by an $8$ kg block. The block is released. It slides on a frictionless surface, up a frictionless hill that is $0\mathrm{.}3$ m tall, and then slides across a short $0\mathrm{.}2$ m path $0\mathrm{.}2$ m long with friction $(\mu =0\mathrm{.}5).$ The block then continues onto a frictionless surface. How fast is the block moving when it continues onto the frictionless surface?
