Answer:

15.97 N force is tending to pull Rover forward

Explanation:

The woman pulls on the leash with a force of 20.0 N at an angle of 37° above the horizontal. The arrangement is shown in the given figure,

We nee to find the pulling force P. The 20.0 N force has two components, 20.0 cos 37 in horizontal direction and 20.0 sin 37 in vertical direction.

The horizontal component is equal to pulling force P, which will pull Rover forward/

So, P = 20.0 cos 37 = 15.97 N

15.97 N force is tending to pull Rover forward.
