Week 2
In Monday's lab, we addressed the question of how to make a race fair if two people run at different speeds. The goal was to try to get both people to finish at the same time. This could be done by one person walking and the other running, the slower person getting a head start, or walking or running at different speeds. We broke out into groups to test theories of how to make the race even before combining groups to test our theories. In Thursday's lecture, we discussed how to calculate how long it would take for two people to finish a race using meters per second. We then calculated how much of a head start the slower person needed in both distance and time to make sure both finished at the same time. We also calculated a biker against a driver to find out a timed head start using miles per hour. Finally, we described a car's motion that left oil drops to figure out when the car was speeding up and slowing down. To finish, we discussed the importance of teaching
