Today we worked through the problem of a roller coaster car that started from rest at the top of a 7.2 meter high hill. We found the total energy, the kinetic and potential energies at three different points, and the point at which the speed of the car is greatest. We then used this problem to go over several similar problems on Concept-Developments 8-1 and 8-2.
Over the next three days, quite a few students will be pulled from class to take AIMS. I don't want these students to miss our introduction to rotational motion, so instead we're going to work on some of those special assignments we taped into our notebooks at the beginning of the year. We'll use topics from the last few weeks.
