Jay- just need help!

The three ropes shown are tied to a small, very light ring that is stationary. Two of these ropes are anchored to walls at right angles with the tensions shown in the figure. What is the magnitude of the tension T3 in the third rope, if T1 = 48.8 N, T2 =...

how do you rearrange this equation weight=T1sin57+[T1cos57/cos23.5]xsin23.5 when you're trying to isolate T1?????

A heavy freight train has a mass of 11800 metric tons. If the locomotive can pull with a force of 691000 N, how long does it take to increase it's speed from 0 to 70.3 km/h? 20.36=V0+5.9x10^-3 =349.1 s is this correct?

oook but would that not be the same answer? a=(20.36-0)/ t t=20.36/.059 probably not how you rearrange it but all the other ways lead to numbers that are much too small
