Tarzan (m = 85 kg) is trying to swing across a river on a long vine. Use angle = 40 degrees and L=10m. Assume that he starts from rest and that there are no resistive forces.
a: Determine the tension in the rope when the angle has been reduced to 30 degrees.
b: Determine the magnitude of his tangential acceleration at the same instant.
c: Assume that the vine will break if its tension needs to exceed 1000 N. Determine whether the vine breaks near the lowest point. (It will break). The answers are in parenthesis, but how do you get those answers?
