    Force on rope

    hi all, Taru and Reiko simultaneously grab a 1.61 kg piece of rope and begin tugging on it in opposite directions. If Taru pulls with a force of 18.0 N and the rope accelerates away from her at 1.24 m/s2, with what force is Reiko pulling? Round your answer to 2 decimal places. My thoughts...

    the ant on a rubber rope

    I cannot solve the problem of the ant on a rubber rope (Ant on a rubber rope - Wikipedia, the free encyclopedia) in the case of a rope stretching exponentially: the target end of the rope y(t) goes away exponentially y(t)= D*exp(H*t) where D and H are positive constants. D is the initial...

    How to work out the angle between a Rope anchor system

    Hello everyone, Just wondering how I work out the angle on a Artificial High Directional. In the photo, the angle I want to work out is between the metal Gin Pole and one of the tie downs connecting it to the hand rail, lets say the Yellow one on the front / right. I'm trying to figure this out...
