A horse is harnessed to a sled having a mass of 226 kg, including supplies. The horse must exert a force exceeding 1170 N at an angle of 34.3 (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 1170 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 5.85 10² N on the sled at the same angle. (Enter the magnitude.)
