A crate having a mass 50.0 kg falls horizontally off the back of
the flatbed truck, which is traveling at 28 m/s. The crate slides
86.8 m on the road in coming to rest. The initial speed of the
crate on the road is the same as that of the truck.
(a). Draw and clearly label all of the forces acting on the
crate as it slides on the road.
(b). Draw the direction of the initial velocity for the...
