Question

In the figure, a 700-kg crate is on a rough surface inclined at 30°. A constant external force = 5600 N is

applied horizontally to the crate. As the force pushes the crate a distance of 3.00 m up the incline, the speed changes from 1.40 m/s to 2.50 m/s. How much work does gravity do on the crate during this process? +10,300 J -3400 J +3400 J -10,300 J zero
