A rope is tied to one end of a 20.0-kg box that is initially at rest as it sits on a horizontal surface. The coefficient of friction between the box and the surface is 0.400. You pull on the rope with a 90.0 N force at an angle of 30.0◦ above the horizontal for 5.00 s. At the end of five seconds, you release the rope and the box slows to a stop.

(a) What is the maximum speed of the box?

(b) What is the total distance the box slides?
