A statue is crated and moved for cleaning. The mass ? of the statue and the crate is 150 kg. As the statue slides down a ramp inclined at an angle ?=40∘, the curator pushes up, parallel to the ramp's surface, so that the crate does not accelerate. The statue slides a distance ?=5.0 m down the ramp, as shown in the figure, and the coefficient of kinetic friction ?k between the crate and the ramp is 0.54. Assume the that positive direction is down the ramp.
