Question

Assume you are on a planet similar to Earth
where the acceleration of gravity is approximately 10 m/s^2

A block of mass 20 kg lies on an inclined plane, as shown. The horizontal and vertical supports for the plane have lengths of 16 m and 12 m, respectively, and the coefficient of kinetic friction between the plane and the block is 0.2. The magnitude of the force F necessary to pull the block up the plane with constant speed is most nearly

Answer 1

I'm trying to help, hopefully i'm right. First, find the angle of incline plane.
