A donkey is harnessed to a sled having a mass of 221 kg, including supplies. The donkey must exert a force exceeding 1190 N at an angle of 38.3 (above the horizontal) in order to get the sled moving. Treat the sled as a point particle. HINT (a) Calculate the normal force (in N) on the sled when the magnitude of the applied force is 1190 N. (Enter the magnitude.) (No Response) N (b) Find the coefficient of static friction between the sled and the ground beneath it. (No Response) (c) Find the static friction force (in N) when the donkey is exerting a force of 5.95 x 102 N on the sled at the same angle. (Enter the magnitude.) No
