Assignments:

• 1. Gavin (11c). In this project, I will use Calculus to determine the best angle to use if you are trying to reach a point that is 10 miles north and 10 miles east of your starting location. If the first half of the hike was a steady mountain and the rest leveled off as the hill plateaued, which initial angle for ascension would be necessary to ensure the fastest hiking time? We can imagine that this could be a contest and the winner would receive a million dollars. There was one problem; everybody hiked at the same pace depending on the inclination of the earth. For this example, I will set the hill velocity at v₁=3 miles/hour and the flat ground velocity at v₂=6 miles/hour. The Pythagorean Theorem will be used to create equations for the two-line segments which represent the hiker’s path. The first line segment (the path that lies on the hill) will be labeled as A and the line that lies on flat ground will be labeled as B. As for the x variable that our equations will be incorporating, it will stand for the distance east that the hiker is at once he completely ascends the hill. The point at which the hill flattens out is 5 miles north from the origin. This means that the minimum distance of the hillside that the hiker will be climbing is 7.07 miles if traveling straight up the hill. This still does not take away at the total displacement of location. The displacement will remain 10 miles away from the origin. I plan to use excel graphs to accurately represent different trials of hikers to prove my answer. The hikers will choose different x values, which will ultimately affect their total hiking time.

• 3. Travis (10b) In this project, the objective is to determine if it was possible for Archimedes to have set fire to Roman ships by redirecting the sunlight with reflective shields. For testing/modeling purposes, I will generate a simulation to test the objective from an Excel and MicrostationV8i. Using the law of reflection and tangencies to accompany my findings, could it have been that Archimedes was successful in his defensive tactic using reflective shields to burn the Roman ships? Ultimately, I will test the objective myself and have a video reference.

• 4. Logan (5b). Can a sailing boat go in the direction opposite to the direction of the wind? For my final project in Calculus class, I have been assigned the action of a sailboat sailing against the flow direction of the wind. The sail of a boat works almost in the same fashion as wings do on a plane. When air flows over a wing from front to back, the wind that flows over the top of the wing travels farther than the wind that travels underneath, which creates a pressure difference, and this is what lifts the plane. For a sailboat, wind blowing at an angle against the boat inflates the sail. The sail forms a similar shape to a plane wing, which creates a difference in pressure that pushes the sail in a direction perpendicular to the wind. Theoretically, this can be done, but it still needs to be tested experimentally. To do this, one would have to calculate the lift/drag ratio, just like one would for a plane wing, where “lift” can be translated into “push”, as well as the angle of attack, α. A sail requires a relatively large value for α, between 15 and 25 degrees, to give enough drive to overcome the total amount of drag from the sail, hull, and keel of the boat.

• 5. Branden (2b). For my calculus project, I have been tasked with trying to find out if a man can run from one table to another without touching the floor by stepping on a bouncing ball. I will attempt to solve this problem by first finding the average and instantaneous velocity of the man as he makes the full run and as he steps on the ball respectively. I will also calculate when the ball must be dropped so that it does not hit the runner, and I will find out how high the ball must be dropped from so that its bounce will bring it to the exact height of the tables so that the runner can cross it. I will be using Microsoft excel to provide a visual representation of my math.
