1. The system is set up in a y shape. A weight of 12kg is hanging from the bottom. One of the angles formed with respect to the x-axis is 25. We are also told the 2 forces are equal.
2. Sum of forces in the x directions = 0. Sum of forces in the y direction = 0. 12kg*9.81 = 117.72N.

I forgot that t, I swear I got it on paper.
I ended up with Xc=.110+95t and Xt=75t, which gave me the right answer, but negative. I tried it again with Xc=95t and Xt=.110-75t and it gave me the 20 sec which is the answer.
If I change it to -.110 would that be the same thing as saying the...
I got a few problems like this one. The only thing I can't figure out is where to put the km. Here's what I got. A car traveling 95km/hr is 100m behind a truck traveling 75km/h. How long will it take the car to reach the truck. My 2 formulas are:
X=Xo+Vo+(1/2)at2
Car: X=95t2
Truck: X=75t2...
