A 700-kg crate slides 300 m down a ramp inclined at 550ordm, Ask an Expert

Academics

A 7.00-kg crate slides 3.00 m down a ramp inclined at 55.0º below the horizontal.

(a) If there is no friction between the crate and the ramp, find the work done by each of the forces acting on the crate. What is the net work done on the crate? What is the crate's speed after sliding 3.00 m if it started from rest?

(b) If the coefficient of kinetic friction between the crate and the ramp is 0.320, find the work done by each of the forces acting on the crate. What is the net work done on the crate? What is the crate's speed after sliding 3.00 m if it started from rest?
