The discussion revolves around calculating the maximum speed Tarzan can tolerate at the lowest point of his swing while crossing a gorge. The problem involves concepts from circular motion and forces, specifically relating to tension and gravitational force.
The discussion is active, with participants questioning the initial setup and assumptions, particularly regarding the inclusion of gravitational force and the implications of Tarzan's weight. Some guidance has been offered about considering the forces acting on Tarzan at the lowest point of the swing.
There is mention of the need for local gravitational acceleration, which has not been explicitly stated in the problem. Participants are also discussing the implications of assuming zero velocity in the context of tension in the vine.
You forgot to consider Tarzans weight.Jade_lowe said:Homework Statement:: Tarzan plans to cross a gorge by swinging in an arc from a hanging vine. if his arms are capable of exerting a force of 1500 N on the vine, what is the maximum speed he can tolerate at the lowest point of his swing? His mass is 80 kg, and the vine is 4.5 m long.
Relevant Equations:: Fmax= mvmax^2/r
T= m*vmax^2/r 1500 = (80kg)vmax^2/4.5
No. It isn’t. Do a free body diagram of Tarzan at the base of the swing.Jade_lowe said:The mass is his weight.
We’ll, they should have stated local ##g## too, but you can assume 9.81 m/s².Jade_lowe said:This is what the question gave me.
