Explanation:
Let's look at the forces on the two axes:
Substituting (2) into (1) and solving for , we get
The force applied to pull the box up the ramp acts parallel to the incline is 8N
The force applied to pull the box is expressed as:
Fm is the moving force
Ff is the force of friction
Get the moving force and frictional fice
The force applied to pull the box up the ramp acts parallel to the incline = 5N + 3N = 8N
Hence the force applied to pull the box up the ramp acts parallel to the incline is 8N
