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:
[tex]F_N = F_m + F_f[/tex]
Fm is the moving force
Ff is the force of friction
Get the moving force and frictional fice
[tex]F_m = 10sin30^0 = 5N\\F_f = 3N[/tex]
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
