| - | You are a member of a scientific research team at McMurdo ice station which is funded by the Carver Media Group in Antarctica. | + | (Skip ahead to Part C for the computational portion of the project. What follows is simply the project's storyline.) |
| - | Two members of your research team have recently returned from investigating an incident at a Norwegian research facility. They brought with them a burnt humanoid body with two faces. Since the disturbing discovery several inhabitants of the ice station have disappeared. Frightened, a member of your team decided to flee the station on a fan powered hovercraft but you receive a distress call not long after their escape that their steering and acceleration controls have been jammed and they need your help. | + | You are a member of a scientific research team at McMurdo ice station which is funded by the Carver Media Group in Antarctica. For reasons undisclosed, several inhabitants of the ice station have disappeared. Frightened, a member of your team decides to flee the station on a fan powered hovercraft but you receive a distress call not long after their escape that their steering and acceleration controls have been jammed and they need your help. |
| - | You decide to attempt a rescue in another hovercraft. You need to tell the runaway researcher the exact time from your starting time to jump onto your hovercraft as you may only have one shot at this rescue. Just as you are about to radio the time to jump to the runaway researcher, you realize the steering and acceleration controls have become frozen on your hovercraft and so it continues to accelerate and you cannot change direction. 200m ahead of the point at which you were going to tell the researcher to jump is an ice ravine. At the bottom of the ice ravine, 400m below, is an unfrozen salt water pool surrounded by stalagmites. From the ravine's edge to the pool is 490m and the pool stretches for 900m. You are moving too quickly to survive jumping off the hovercraft, but might survive the fall into the pool by staying on the hovercraft; it has seat belts. You now have a choice to make, to stay on your hovercraft or jump to the runaway researcher's hovercraft. One or both may make it to the pool. Your choice may be the difference between life and death. | + | You decide to attempt a rescue in another hovercraft. You need to tell the runaway researcher when to jump onto your hovercraft.

| Surprisingly enough hovercrafts are an expensive piece of kit. Your employer, the Carver Media Group, is concerned by the happenings at the McMurdo ice station and would like you to produce an accident report detailing the events after you lost control of your hovercraft. The accident report should include a detailed computational model that provides the projected motion of the runaway hovercraft. | Surprisingly enough hovercrafts are an expensive piece of kit.
