Today in class we went over the two assignments on roller coasters that we have been working on all this week. We started off by writting our answers to question 3 letters B and C for Mr. Manning to collect. Then, we went over a few daily questions. The first was a person throwing a ball off of a cliff at three different angles and the same speed. The question asked whech one hit the ground first. The answer was actually that all three balls hit at the same time. The next question had 2 balls rolling at the same speed, but one went uphill, then downhill, and the other was the exact opposite. The question asked which one finished in the least amount of time. The answer was the second scenario in which the ball went downhill first. After this, we reviewed the two roller coaster sheets. Mr. Manning put his answers on the smart board along with the work for each problem. Then we went over the graphs for the K'NEX rolller coaster demo lab.
