A big box of mass M sits motionless on the floor. A smaller box of mass m sits on the big box. The coefficient of static friction between the boxes is mu. A rope is attached to the big box.

Joe starts to pull the rope to the right.

  1. What is the largest force Joe can exert without causing the little box to slide backwards off the big box?
  2. Suppose Joe pulls with this force. How fast will the boxes be moving t = 5 s later?
  3. Suppose Joe pulls with this force. How fast will the boxes be moving d = 10 m later?

Let's move on ...
