Tarzan `(m = 85.0 kg)` tries to cross a river by swinging on a vine . The vine is `10.0m` just and his speed at the bottom of the swing (as he just clears the water) will be `8.00 ms^(-1)` Tarzan does not know that the vine hasa breaking strenght of `1000 N` Does he make it across the river safely ?

Explanation

To determine whether Tarzan can safely cross the river using the vine, we need to analyze the forces acting on him at the lowest point of the swing. Here’s a step-by-step solution:

### Step 1: Identify the Forces Acting on Tarzan
At the lowest point of the swing, two forces act on Tarzan:
1. The gravitational force (weight) acting downwards, which is given by \( F_g = mg \).
2. The tension in the vine acting upwards, which we will denote as \( T \).

### Step 2: Calculate the Gravitational Force
