A box is dropped onto a conveyor belt moving at 3.4 m/s. If the coefficient of friction between the box and the belt is 0.27, how long will it take before the box moves without slipping?
A box rests on the horizontal trailer of a truck. The coefficient of static friction between the box and the surface of the trailer is 0.24. The truck starts from rest and moves horizontally with constant acceleration. What maximum distance can the truck travel in 3.0 s without the box starting to slide?
