Awooden crate of mass m = 70 kg slides horizontally off the back of a flatbed truck traveling at 80 km/hr. determine the kinetic coefficient of friction between the road and the crate if the crate slides (without tumbling) a distance of d = 50 m on the ground before coming to rest. assume the initial speed of the crate is the same as that of the truck.
