Problem
A refrigerator has a mass of 150 kg and rests in the open back end of a delivery truck. If the truck accelerates from rest at 1.5 m/s², what is the minimum coefficient of static friction between the refrigerator and the bed of the truck that is required to prevent the refrigerator from sliding off the back of the truck?
