Final answer:
The bungee cord will first touch the corner of the building at the highest point.
Step-by-step explanation:
In this scenario, the bungee cord will first touch the corner of the building at the highest point. When a bungee jumper falls, they experience a motion often described as a simple harmonic motion. This means their motion follows a sinusoidal pattern with a maximum point at the highest point of the fall.
When the bungee jumper reaches the highest point, their velocity momentarily becomes zero. At this point, the bungee cord will be fully stretched out and will reach the corner of the building.
Therefore, the correct answer is A) At the highest point.
