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 crate on the road.
(c). What is the acceleration of the crate as it slides on the road?
(d). Find the value of the coefficient of kinetic friction between the road and crate
(e). Sketch the v(t) and a(t) plots for the crate on the road,
starting with the moment it lands on the road.
