A crate with a mass of 3.00 kg starts from rest at the top of a 28.0° incline and slides 2.00 m down the incline in 1.25 s.

(a) What is the magnitude of the acceleration of the crate (in m/s2)?

2.56 m/s2 correct

b) What is the frictional force (in N) acting on the crate? (Enter the magnitude.)

(c) What is the coefficient of kinetic friction between the crate and the incline?

(d) What is the speed of the crate (in m/s) after it has slid 2.00 m? m/s

A 30-kg crate starts from rest, slides down a frictionless incline and then along a rough horizontal surface until it comes to rest. The coefficient of kinetic friction between the horizontal surface and the crate is 0.27. If the crate’s initial height is 9 m, find the distance it travels on the horizontal surface.
