This week’s immunity challenge is to dive into a lake and release a weighted buoy. Each contestant is given three chances, and the person who releases the deepest buoy will win immunity for the week, while the person who releases the shallowest buoy will be voted off the island. Your task is to determine all those who will move onto next week’s challenge.
h is the height above the water’s surface in meters, and t is the time in seconds.
Carlos: h = 0.5t2 – 5t.
Frank: h = t(t - 8).
Raji: 4h + 12t = t2.
Ella: h = 0.6(t – 4)2 – 10.
Record each contestant’s depth next to their name.
The person with the shallowest dive will be voted off the island.
