# Problem: 1. A block of mass 2 kg is acted upon by two forces: 3 N (directed to the left) and 4 N (directed to the right). What can you say about the block's motion?a. It must be moving to the left.b. It must be moving to the right.c. It must be at rest.d. It could be moving to the left, moving to the right, or be instantaneously at rest.which one is the answer? there can be more than one answer......2.

1.

The magnitude of the forces acting on the block are not equal. The forces are also in the opposite direction.

Thus, the block could move to the left, or right, or it will be instantaneously at rest.
