A Tarzan swing Tarzan (mass 80 kg) swings at the end of an 8.0-m-long vine (Figure P4.55). When directly under the

vine’s support, he releases the vine and flies across a swamp. When he releases the vine, he is 5.0 m above the swamp and 10.0 m horizontally from the other side. Determine the force the vine exerts on him at the instant before he lets go (the vine is straight down when he lets go).
