Question Part Points Submissions Used A horse is harnessed to a sled having a mass of 241 kg, including supplies. The horse must exert a force exceeding 1230 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 1230 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 6.15 102 N on the sled at the same angle. (Enter the magnitude.)

Explanation / Answer

a] Normal N= Mg - F sin theta

= 241*9.8 - 1230* sin 38.3 degree

= 1600 N answer

b] Here we have uN = F cos theta

u = F cos theta/N = 1230 cos 38.3 degree /1600

= 0.603 answer

c] Here sled will not move, so Friction force = F horizontal

= 615* cos 38.3 degree

= 483 N answer
