A hockey player hits a puck with his stick, giving the puck an initial speed of 5.0 m/s. If the puck slows uniformly and comes to rest in a distance of 20 m, what is the coefficient of kinetic friction between the ice and the puck?

Frictionforce*distance=1/2 m vi^2
mu*mg*distance=1/2 m vi^2
solve for mu.
