10. [-/1 Points] DETAILS SERCP11 4.4.P.027. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A donkey is harnessed to a sled having a mass of 261 kg, including supplies. The donkey must exert a force exceeding 1200 N at an angle of 34.30 (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 1200 N. (Enter the magnitude.) IN (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 donkey is exerting a force of 6.00 x 102 N on the sled at the same angle. (Enter the magnitude.) N Need Help? Read It Watch It
