A flatbed truck has a box on its bed. The box is not bolted down
or tied. It just sits there. The truck accelerates in a forward
direction, and the box goes with it. What direction is the force of
friction acting on the box?
A) forward
B)backward
C)there is no force of friction
Explain why you chose the answer you did.
Homework Answers
Due to the inertia of the box it will wants to be remain in that position, but the track will move in foward direction so box will move in backward direction relative to the flatbed track. So force of friction will acts opposite to the motion of the box.. so the friction force will be in forward direction. So option A) is correct.

A large truck is carrying a heavy load. A significant hazard for the driver is that the load may slide forward, crushing the cab, if the truck stops suddenly in an accident or even in braking. Assume a 10,000 kg load sits on the flatbed of a 20,000 kg truck moving at 12 m/s. Assume the load is not tied down to the truck but has a coefficient of friction 0.5 with the flatbed of the truck. Calculate the minimum...

A box rests on top of a flat bed truck. The box has a mass of m = 20 kg. The coefficient of static friction between the box and truck is mu_s = 0.86 and the coefficient of kinetic friction between the box and truck mu_s = 0.67. The truck accelerates from rest to v_f = 19 m/s in t = 12 s (which is slow enough that the box will not slide). What is the acceleration of the box?...
