Tarzan plans to corss a gorge by swinging in an arc form a hanging vine. If his arms are capable of exerting a force of 1400 N on the rope, what is the maximum speed he can tolerate at the lowest point of his swing? his mass is 80 kg and the vine is 4.8 m long.
Ok If i\'m correct...
Fg is the only force acting downards
all point upwards
how do i solve this wihout doing any rotational kinematics thanks
not sure what the force of tension is equal to in this problem
