A child on a sled reaches the bottom of a hill with a velocity of 10.0m/s and travels 25.0m along a horizontal straightaway to a stop. If the child and sled together have a mass of 60kg, what is the average retarding force on the sled on the horizontal straightaway?.

Vf^2 = Vo^2 + 2a*d = 0.
a = -(Vo^2)/2d = -(10^2)/50 = -2.0 m/s^2

F = M*a = 60 * (-2.0)=-120 N. Retarding force.
