Asked by Kayla L
A crate starts from rest and slides 8.35 m down a ramp. When it reaches the bottom it is traveling at a speed of 5.25 m/s. The ramp makes an angle of 20.0o with the horizontal.
b) What is the coefficient of kinetic friction between the crate and the ramp?

PE loss = KE gain + work againat friction
M g *8.35*sin20
= (M/2)*Vfinal^2 + 8.35*M*g*cos20*mu_k
Cancel the M's and solve for mu_k
