A block weighing 83.3 N rests on a plane inclined at 26.3 degrees to the horizon

Question

A block weighing 83.3 N rests on a plane inclined at 26.3 degrees to the horizontal. The coefficient of the static and kinetic frictions are 0.22 and 0.14 respectively.

a) What is the minimum magnitude of the force F, parallel to the plane, that will prevent the block from slipping?
I know you use Net force = m*a=0 (since horizontal) anf F min + F frict = sin and therefore F min = sin - Fs

b) What is the minimum magnitude of F that will start the block moving up the plane?

c) What is the magnitude of F required to move the block up the plane at constant velocity?
I know you use F = sin + uk N

Explanation / Answer

a. use kinetic frictions b.use static friction coefficient c.kinetc fricetion and velocity acceleraton relations c.
