Question

Tarzan swings from a vine. at the bottom of the swing, what is the direction of the net force acting on tarzan?

Answer 1

Towards the center

Step-by-step explanation:

Tarzan undergoes circular motion so the net force toward the center acting on him is required. Thus, the tension in the vine is greater than the gravitational force on Tarzan.

Answer 2

The net force is pointing up the vine towards the center of its swinging. This is the centripetal force. Gravity is also acting on Tarzan pulling directly downward.
