A ramp that is 3.25m long leads up to a platform which is 1.25m high. A cubic packing
case of side length 1m that weighs 50kg stands at the top of the ramp. It is held in position
by a rope held parallel to the ramp.
(a) If the coefficient of static friction is 0.35, what is the tension in the rope?
I am trying to understand the solution to this problem, but I don't understand the part where values of
how were these values obtained?
