luke skywalker must swing princess leia across a large chasm in order to escape the storm troopers. IF luke and leia's combined mass is 145 kg calculate the tension in the rope just before luke and leia start their swing when the pair makes an angle of 30.0 with the vertical/

Draw a vector diagram.
You should have mg downward (where m is the combined mass).
Then tension is along the rope, so ..lets see....Tension is mg/cosTheta
Check that.
