A block with mass m $=3\mathrm{.}63$ is placed against a spring on a frictionless incline with angle $=39\mathrm{.}1$ degrees. The spring, with spring constant k $=19$ N$/$cm$,$ is compressed $24\mathrm{.}9$ cm and then released. $($a$)$ What is the elastic potential energy of the compressed spring? $($b$)$ What is the change in the gravitational potential energy of the block$-$Earth system as the block moves from the release point to its highest point on the incline? $($c$)$ How far along the incline is the highest point from the release point?
