Please help! Any help at all. Please! ;(
Two boxes are being pulled up a 30.0 degree ramp with a cable at a constant velocity. Box 1 (weight of 44.1 N) is attached to the cable and also has a chain which is attached to Box 2 (34.3 N) being dragged behind Box 1. Assume a coefficient of kinetic friction, mu(k) = 0.250, for all surfaces.
What is the friction between Box 1 and the ramp in newtons?
What is the friction between Box 2 and the ramp?
What is the acceleration of the boxes?
What is the tension in the chain?
What is the tension in the cable?

Best ResponseYou've already chosen the best response.2dw:1357959301874:dw @pathosdebater You need to figure out the angle between gravity and the normal, or gravity and the tension, whichever is easier for you.

Best ResponseYou've already chosen the best response.2There are only three main forces at play here: 1) gravity 2) normal 3) tension

Best ResponseYou've already chosen the best response.0I'm taking this class for fun online (since it is a few grades above my current one) and I want to show the teacher I have what it takes to stay in the class. I was out of town and wasn't able to study for the test. Please help me fast. (It's timed). I really want to stay in the class.

Best ResponseYou've already chosen the best response.2Thus the angle between gravity and tension is going to be 60

Best ResponseYou've already chosen the best response.2Now using trig you can convert your gravity force into it's normal component and tension component.

Best ResponseYou've already chosen the best response.2Normal components can be used to calculate force, and then tension obviously will tell you tension.
