Question

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?

Answer 1

@pathosdebater You need to figure out the angle between gravity and the normal, or gravity and the tension, whichever is easier for you.

Answer 2

There are only three main forces at play here:
1) gravity
2) normal
3) tension

Answer 3

I'm not sure what you mean?

Answer 4

I'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.
