Question

A block of mass 2kg is acted upon by two forces: 3N (directed to the left) and 4N (directed to the right). What can you say about the block's motion?

It could be moving to the left and speeding up.

It could be moving to the left and slowing down.

It could be moving to the right and slowing down

It could be permanently at rest.

Explanation / Answer

There are three options are correct for this statement.

These are :

-It could be moving to the left and slowing down.

-It could be moving to the right and slowing down

-It could be permanently at rest.

The acceleration of an object tells you nothing about its velocity -the direction and speed at which it is moving.

In this case, the net force on (and therefore the acceleration of) the block is to the right, but the block could be moving left, right, or in any other direction.
