Problem
A gardener pulls a 15kg garden sled along level ground by means of a rope that makes an angle of 25∘ above the horizontal. The coefficient of kinetic friction between the sled and the ground is 0.15. The sled moves at constant velocity.
(a) Draw and label a free-body diagram for the sled while it is being pulled.
(b) Determine the magnitude of the tension needed in the rope to maintain the sled’s constant velocity.
(c) Calculate the magnitude of the normal force exerted on the sled by the ground while the gardener is pulling it.
