Sorry people, not sure where I am going wrong, I am just not sure in which direction to take this question. I don't even know where to start.
A box with mass of 22kg is at rest on a ramp inclined at 45 degrees to the horizontal. The coeffecient of friction between the box and ramp are (Static friction = 0.78, Kinetic Friction = 0.65)
a) determine the magnitude of the largest force that can be applied upward, parallel to the ramp, if the box ix to remain at rest
b) determine the magnitude of the smalled force that can be applied onto the top of the box, perpendicular to the ramp, if the box is to remain at rest
