Physics

A 50 kg crate slides down a ramp that is inclined by 30 degreesfrom the horizontal. The acceleration of the crate parallel to thesurface of the ramp is 2.0m/s^2, and the length of the ramp is10m.

Determine the kinetic energy accumulated by the crate when itreaches the bottom of the ramp if it started from rest at the topof the incline.

Calculate the amount of energy lost by the crate due to frictionin its journey down the ramp.

Compute the magnitude of the frictional force that acts on thecrate as it slides down the ramp and calculate the coefficient ofkinetic friction between the ramp and the crate.
