Answer number 3 

n = mg = 35 kg x 9.8 m/s² = 343 N fs = Hs n = 0.50 x 343 N = 171.5 N Fp = fs = 171.5 N 2. A boy exerts 50.0 N to push an object across a horizontal surface at constant velocity. If the object has a mass of 10.0 kg, what is the coefficient of kinetic friction between the object and the surface? 3. How much force is needed in Problem 2 if the boy exerts the force at an angle of 30.0° above the horizontal. The coefficient of sliding friction between a 50.0 kg ice and the pavement is 0.06. What force is needed to move the ice at constant speed across the pavement? 4.
