A 4.6-kg block slides down an inclined plane that makes an angle of 26° with the horizontal. Starting from rest, the block slides a distance of 2.6 m in 4.9 s. Find the coefficient of kinetic friction between the block and plane.

find the acceleration down the plane
distance=1/2 a t^2 solve for a.

Then, summing forces on the plane

forcedown-friction=ma
mg*sinTheta-mg*cosTheta*mu=ma

solve for mu.
