Question

Four friends push on the same block in different directions. Allie pushes on the block to the north with a force of 18 N. Bill pushes on the block to the east with a force of 14 N. Chris pushes on the block to south with a force of
23 N. Debra pushes on the block to the west with a force of 20 N. Assuming it does not move vertically, in which directions will the block move? (1 point)
south and west
north and east
• south and east
north and west

Answer 1

Net north-south = 18 N north − 23 N south = 5 N south.
Net east-west = 14 N east − 20 N west = 6 N west.

So the block will move south and west (resultant ~7.81 N, ≈39.8° south of west).
