An $8\mathrm{.}0$ kg crate is pulled $5\mathrm{.}0$ m up a $30$ incline by a rope angled $18$ above the incline. The tension in the rope is $120$ N$,$ and the crate$$s coefficient of kinetic friction on the incline is $0\mathrm{.}25.$ a$.$ How much work is done by tension, by gravity, and by the normal force? $[0\mathrm{.}0$ J$]$ b$.$ What is the shape of the trajectoryb. What is the increase in thermal energy of the crate and incline? $[$
