A: Applying Newton's laws to interacting objects which velocity are moving with a constant A factory worker is pushing two touching crates across the floor. The crates move at a constant velocity since there is kinetic friction between each crate and the floor. You may assume that the coefficient of kinetic friction between each crate and the floor is the same. 3M M on M to that on 3M. Explain your ans Compare the net force (magnitude and direction) 1....

1. A helicopter is lifting two crates simultaneously. Crate A, with a mass ma, is attached to the helicopter by a light cable (cable #1). Crate B, with a mass me, hangs below crate A and is attached to crate A by a second light cable (cable #2). The cables are NOT connected. The helicopter accelerates upward with an acceleration of magnitude a. Ignore all frictional effects. Let T be the tension in cable #1 and Tbe the tension in...

diagram, derive an expression for the normal force exerted on the
block by floor.
- Assess you answer in the following way: If you
let \(\theta\) = 0, what does your
solution predict for the normal force? Does this make physical
sense?

4. Newton's Third Law You will now attempt to measure the forces objects exert on each other when the objects interact and the effects those forces have on the motion of the objects. In this section, you will use both force sensors on two carts and conduct a series of force measurements during (gentle) tug-of-war tests. 4.1: Suppose you have two carts, A and B. Both are made of the same material, and B is more massive (heavier) than A....
