Let's consider the block's free-body diagram below:
A box of mass m is on a rough inclined plane that is at an angle theta with the horizontal. A force of magnitude F at an angle ф with the plane is exerted on the block as shown above as the block moves up the plane there is a frictional force between the plane and magnitude F what is the magnitude of the net force acting on the box?
a. F sinф - mgcos θ - f
b. F cos (ф+θ) + mgsin θ - f
c. F cosф - mgsin θ - f
d. F cos (ф+θ) - mgsin θ - f
