Question

A statue is crated and moved for cleaning. The mass mm of the statue and crate is 150kg150kg. As the statue slides down a ramp inclined at an angle θ=40∘θ=40∘, the curator pushes up, parallel to the ramp's surface, so that the crate does not accelerate. The statue slides a distance d=4.0m d=4.0m down the ramp, as shown in the figure, and the coefficient of kinetic friction μkμk between the crate and the ramp is 0.580.58. Assume that the positive direction is down the ramp.

a) Calculate the work WgravWgrav done by the gravitational force. (b) Calculate the work WfrictionWfriction done by the friction force. (c) Calculate the work WcuratorWcurator done by the curator. (d) Calculate the work WnormalWnormal done by the normal force.
