Question
At one moment during a walk around the block, there are four forces exerted upon Fido – a 10.0 kg dog. The forces are:
Fapp = 67.0 N at 30.0° above the horizontal (rightward and upward)
Fnorm = 64.5 N, up
Ffrict = 27.6 N, left
Fgrav = 98 N, down
Resolve the applied force (Fapp) into horizontal and vertical components. Then add the forces up as vectors to determine the net force.

Explanation:
Given that,
Fapp = 67.0 N at 30.0° above the horizontal (rightward and upward)
Fnorm = 64.5 N, up
Ffrict = 27.6 N, left
Fgrav = 98 N, down
(a) Resolution of the applied force:
Horizontal component,
Vertical component,
(b) Net horizontal force :
It is positive, it will act in right side
Net vertical force :
Hence, it is clear that the net force is in horizontal direction i.e. 30.42 N due right side.
