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? How much force is needed in Problem 2 if the boy exerts the force at an angle of 30.0° above the horizontal. Show the free-body diagram and sketch of the given.
