Question

A box slides down a 26° ramp with an acceleration of 1.19 m/s2. Determine the coefficient of kinetic friction between the box and the ramp.μk =

Answer 1

net force down ramp=mass*a

net force=gravitycomponnetdown ramp-friction
net force= mg*sinTheta-(mgcosTheta*mu)
ma= mg*sinTheta-(mgcosTheta*mu)
solve for mu
