Compute the amount of force acting on the doghouse using the vector addition rule.

Responses

0 N, the doghouse remains at rest.

20 N, the doghouse remains at rest.

0 N, the doghouse starts moving in one direction and then slows to a stop.

70 N, the doghouse remains at rest.

3 answers

The amount of force acting on the doghouse can be computed by using the vector addition rule. In this case, there are two forces acting on the doghouse - one pushing upwards with a force of 25 N and one pushing downwards with a force of 25 N.

Since these two forces are equal in magnitude but opposite in direction, they cancel each other out. Therefore, the net force acting on the doghouse is 0 N. As a result, the doghouse remains at rest.

So, the correct answer is: 0 N, the doghouse remains at rest.
