Q:

A block weighing 77.3 N rests on a plane inclined at 25.5 deg to the horizontal. The coefficient of the static and kinetic frictions are 0.27 and 0.11 respectively. What is the minimum magnitude of the force (F), parallel to the plane, that will prevent the block from slipping?

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

What is the magnitude of F required to move the block up the plane at constant velocity?
