m A box rests on top of a flat bed truck. The box has a mass of m = 16 kg. The coefficient of static friction between the box and truck is is = 0.82 and the coefficient of kinetic friction between the box and truck is Hk = 0.64. 1) The truck accelerates from rest to Vp = 19 m/s in t = 13 s (which is slow enough that the box will not slide). What is the acceleration...
