A truck of mass M=1200kg is moving up a hill with constant acceleration a. A blok of mass m=3.3kg is held in place by static friction, with coefficient of friction to be .56 between te block and truck bed. The hill is inclined at angle=22o with respect to the horizontal. What is the max acceleration the truck can have before the block will slip?
