Figure 1 of 1

Tarzan (mass 80kg ) swings at the end of an 8.0-m -long vine shown in the figure(Figure 1) . 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.

Explanation / Answer

At the bottom, the vine must support the weight and the centripetal force

F = mg + mv2/r

We need to find v

In the vertical direction, apply

d = vot + .5at2 to find the time

5 = 0 + .5(9.8)(t)2

t = 1.01 sec

Then in the x direction d = vt

10 = v(1.01)

v = 9.90 m/s

Finally F = (80)(9.8) + (80)(9.9)2/8

F = 1764 N
