A flatbed truck of mass 2000kg traveling 20 m/s (about 45mph)carries a load of mass 500kg positioned 3 meters behind the cab. The load is kept on the truck by friction, and the coefficient of friction between the load and the bed of the truck is 0.5. What is the shortest distance in which the truck can stop without having the load slide forward enough to hit the cab? (Note that the load can slide forward 3 meters before it hits the cab.)Please show work.Help!
