Question

18. (II) Tarzan plans to cross a gorge by swinging in an arc

from a hanging vine (Fig. 5-42).
If his arms
are capable of
exerting a force of 1150 N on
the vine, what is the maximum
speed he can tolerate at the
lowest point of his swing? His
mass is 78 kg and the vine is
4.7 m long.

Answer 1

Answer:his weight plus the centripetal force must equal 1170 N

Explanation:

83.0 [g + (v^2 / r)] = 1170

v^2 / 18.0 = (1170 / 83.0) - 9.81
