(Figure 1) shows a 5.4 N force pushing two gliders along an air track. The 150 g spring between the gliders is compressed. The spring is firmly attached to the gliders, and it does not sag. How much force does the spring exert on glider A? Express your answer with the appropriate units. How much force does the spring exert on glider B? Express your answer with the appropriate units.
By pulling on a rope attached to the box, a clerk moves an Oreo crate with a mass of m down an aisle with a frictionless floor. Using force F, the clerk pulls the lever at an angle of 0(theta) to the horizontal. When there is friction, would it be easier for the cashier to press the Oreos downward and draw them upward? Show the evidence.
