1. An object has a mass of 20.0 kg and a coefficient of friction of 0.40. Find the force of friction in this situation. 2. An object is known to have a coefficient of kinetic friction (µk) of 0.167 and a coefficient of static friction (µs) of 0.42. If the normal force is 200.0 N, how much frictional force will it encounter while it is moving? 3. An 80.0 kg object has a µk = 0.35 and a µs...

Three forces act on a moving object. One force has a magnitude of 78.6 N and is directed due north. Another has a magnitude of 55.3 N and is directed due west. What must be (a) the magnitude and (b) the direction of the third force, such that the object continues to move with a constant velocity? Express your answer as a positive angle south of east.
