Okay, I've looked over all of my formulas numerous times and I just can't figure out what to do for these two:
In terms of Earth radii, how far from the center of the Earth would you have to travel in order to cut your weight from 900N to 300N?
The gravitational force between two...
Okay, I worked that out on paper and got it, but I'm having one heck of a time trying to figure out the second hanging sign problem. Do I need to find the two equations and substitute one in for the other? For the second one right now I have:
T2= -T1cos170/cos35 and T1=4900-T2sin35
Do I...
Okay, we've been studying this for a while but I still always seem to forget how to do these and they aren't anywhere in my Physics book.
Problem 1: Sign hanging at rest from two cables. One is angled at zero degrees while the other is at 135 degrees. The sign is 10kg. Find the tension...
