A 80.0-kg skier starts down a 100-m high, 15.0° slope on regular skis. The coefficients of friction between the ski and snow are µs = 0.250 and µk = 0.150. What is the magnitude of the net force on the skier, in Newtons? Use g = 10.0 m/s². Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
