Inclined Planes with Friction Video Lessons

Concept

# Problem: 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 - fb. F cos (ф+θ)  + mgsin θ - fc. F cosф  - mgsin θ - fd. F cos (ф+θ)  - mgsin θ - f

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
