5. A 3.00 kg mass is initially at rest at the bottom of an incline of 35.0°. An applied force begins acting on the mass, pushing it up the incline with a constant force of 25.0 N, directed parallel to the incline. a) If the acceleration produced is 2.50 m/s? up the incline, what must the coefficient of kinetic friction be? b) If the applied force acts for 2.00 s, how far up the incline will the mass travel upon coming to rest?

A man pulls a 50.0-kg block of ice with a rope over his shoulder as shown below. Suppose that he applies just enough force to get the block moving and then he continues to apply the same force. If it takes 2.00 seconds for the block to move 3.00 meters and if the coefficient of kinetic friction between the block and the surface is ?? =0.100, determine the coefficient of static friction ?? between the block and the surface. You may assume that the acceleration of the block is constant.
