Question

A horse is harnessed to a sled having a mass of 211 kg, including supplies. The horse must exert a force exceeding 1200 N at an angle of 38.3° (above the horizontal) in order to get the sled moving. Treat the sled as a point particle.

 

(a)

Calculate the normal force (in N) on the sled when the magnitude of the applied force is 1200 N. (Enter the magnitude.)

N

(b)

Find the coefficient of static friction between the sled and the ground beneath it.

(c)

Find the static friction force (in N) when the horse is exerting a force of 6.00 ✕ 102 N on the sled at the same angle. (Enter the magnitude.)
