A packing crate is at rest on a horizontal surface. It is acted on by three horizontal forces: 600 N to the left, 200 N to the right, and static friction. The weight of the crate is 400 N. If the 600-N force is removed, the net force acting on the crate is

Two blocks are stacked as shown inside a vacuum chamber. The bottom surfaces of theblocks are notably rough. The top block (block A) is pushed with a force F. The blocksdon’t move. Consider all the forces (if any) acting on block B in this situation. In total, how many forces act on block B in the horizontal and vertical directions?

A 6.00-kg block is in contact with a 4.00-kg block on a horizontal frictionless surface as shown in the figure. The 6.00-kg block is being pushed by a horizontal 20.0-N force as shown. What is the magnitude of the force that the 6.00-kg block exerts on the 4.00-kg block?
