A crate of oranges weighing 164 N rests on a flatbed truck 2.0 m from the back of the truck. The coefficients of friction between the crate and the bed are μs = 0.30 and μk = 0.20. The truck drives on a straight, level highway at a constant 7.6 m/s
a) What is the force of friction acting on the crate?
b) If the truck speeds up with an acceleration of 1.6 m/s2, what is the force of the friction on the crate?
What is the maximum acceleration the truck can have without the crate starting to slide?
