Homework Statement
A 25 kg object is being lifted by pulling on the ends of a 1.00 mm diameter nylon string that goes over two 3.10 m high poles that are 4.5 m apart, as shown in Figure 9-87. How high above the floor will the object be when the string breaks?

Could someone explain this problem a little better to me.
Problem:
Calculate the net torque about the axle of the wheel shown in Fig. 8-39. Assume that a friction torque of 0.45 m·N opposes the motion and that F = 18.

I'm confused...
I know that, but I'm still confused.
Since the equation is: Fg = G m1m2/r^2
if I plug in the numbers I'm given:
Fg=2.5e-10
G=6.67e-11
r=0.25
I have: 2.5e-10 = 6.67e-11 m1m2 / 0.25^2.
I solve for m1m2, which is: m1m2 = (Fg*r^2)/G , right?
Doing that, I have m1m2 =...
Hello, I'm trying to solve a problem, but I'm doing something wrong.
This is the problem out of my Physics book, but the problem I'm working on has different numbers, so any help will not be cheating, I just need to know the process.
Problem:
Two objects are attracted to each other...
