Problem $4$:

A constant applied farce is exerted on a block of mass $m=5\mathrm{.}0kg$ so that this block slides with a constant velocity for a certain distance $d=2\mathrm{.}0m$ along the surface of the ramp; as shown in the ligure. $($The block slides up the ramp.$)$ Suppose that this block can be modeled as a point particle. And this ramp is frictionless. The angle of inclination for this ramp is $=65$ degrees.

What is the wark done by the qravitational force an this block during this process describod in above?
