Problem: A horse pulls a 300-kg sled at constant speed over level snow by a rope that is 35° above the horizontal. If the coefficient of kinetic friction is 0.10, find the force the horse exerts on the rope. (Answer: T = 335.42 N)

Step 1
Step 1: Draw a free body diagram of the sled showing all the forces acting on it: weight (mg) acting downward, normal force (N) acting upward, tension force (T) acting at an angle of 45 degrees above horizontal, and frictional force (f) acting to the left. Show more…

A horse is harnessed to a sled having a mass of $236 \mathrm{kg},$ includ- ing supplies. The horse must exert a force exceeding 1240 $\mathrm{N}$ at an angle of $35.0^{\circ}$ in order to get the sled moving. Treat the sled as a point particle. (a) Calculate the normal force on the sled when the magnitude of the applied force is 1 240 N. (b) Find the coefficient of static friction between the sled and the ground beneath it. (c) Find the static friction force when the horse is exerting a force of $6.20 \times 10^{2} \mathrm{N}$ on the sled at the same angle.

A horse pulls a 350-kg sled at constant speed along an icy road for a distance of 500 m. If the coefficient of kinetic friction between the sled and the road is 0.450, and the angle between the harness and the sled is 25°, what is the mechanical energy lost due to friction?

The force of kinetic friction between a sled and the snow on a level trail is 25.0 N. The sled is being pulled at a constant speed by a rope attached to the front of the sled. The force is exerted on the rope at an angle of 32.0° above the horizontal. In order to keep the sled moving at a constant speed, the applied force on the rope Must be more than 25.0 N Must be exactly 25.0 N Must be less than 25.0 N but not 0 N Must be 0 N
