Today in class we had wooly day. It was also a club day, so the period was only around thirty minutes long. It was finaly our chance to try and kill the wooly momoths that we got in class at the begining of the week. First, we had to find the vertical and horizontal displacement of the ball off of the ramp. After that, we used the numbers that we found to find the time it took for the ball to reach the ground. We used the time and the horizontal displacement to find the speed of the ball. Then, we were given a set height that we had to hit our mamoth at. The heights were made by stacking books, setting the mammoth on a chair, or setting the mammoth on a stool. We then had to find the time it would take for the ball to hit the mamoth. Then we used our new time and the speed that we found in the first problem to find our new horizontal displacement. After we found this, we placed our wooly mamoth at that distance and rolled the ball down the ramp and hit it. Our grades were based on if our work was correct, and how close we were to hitting the circle on the mammoth's head. If we were within .25 centimeters of the center, we received two extra credit points. The farther your shot was away from the center, the less and less points we were to receive.
