Problem
A 4.0kg sled is pulled along a horizontal snow track by a rope that exerts a constant horizontal force of 30N toward the right. The coefficient of kinetic friction between the sled and the snow is 0.15. Take g=9.8m/s2.
(a) Calculate the magnitude of the kinetic friction acting on the sled.
(b) Determine the acceleration of the sled, stating its direction.
(c) Starting from rest, how much time will the sled take to reach a speed of 6.0m/s?
