Homework Statement
A large box containing your new computer sits on the bed of your pickup truck. You are stopped at a red light. The light turns green and you stomp on the gas and the truck accelerates. To your horror, the box starts to slide toward the back of the truck. (Assume that the truck is accelerating to the right.)
part 1)
Draw clearly labeled free-body diagram for the box
given the following vectors:
1] weight of box
2] normal force
3] box's friction force on the truck
4] unlabelled vector
part2)
Draw clearly labeled free-body diagram for the truck.
(The bed of the truck is not frictionless.)
given the following vectors:
1] reaction force to tires' backward push
2] normal force from ground
3] weight of truck
4] reaction to the normal force on the box from the truck
5] the box's friction force on the truck
6] unlabelled vector
part a attempt is
weight downwards
normal force upwards
box's friction force on the truck to the right
unlabelled vector (not sure it used as a accelerating vector of the box) to the left
part b attempt is
1] reaction force to tires' backward push - to the right
2] normal force from ground - upwards
3] weight of truck - downwards
4] reaction to the normal force on the box from the truck - upwards
5] the box's friction force on the truck - to the left
6] unlabelled vector - to the right
i am not sure of the answers...
