On March 31, 2009 in room 019, beginning at 9:41 ante meridiem, Christopher Manning, a science teacher, had his third period class complete a variety of activities over the course of 48 minutes. The class began with a homework review, after the students picked up a half sheet of paper and a woolly lab from the front desk. The review consisted of going over the homework pages ten and eleven. Manning reviewed questions 2, 3, and 4 he did not collect the homework or check it. Following the homework review Manning talked a little about Woolly Day, where students will have to hit a target woolly mammoth in the head with a rolling projectile. To do this the students need to calculate different variables to determine what they have to do to the ball to make it hit a one centimeter target. Following his brief hiatus due to the explanation Manning returned to classwork having students do a daily question. The question read as: A cargo plane is flying horizontally at an altitude of 1200 meters with a speed of 150 m/s when a battle tank falls out of the rear loading ramp….. 1. How long does it take the tank to hit the ground? 2. How far horizontally is the tank from where it fell off when it hits the ground? 3. How far is the tank from the aircraft when the tank hits the ground, assuming that the plane continues to fly with a constant velocity? Manning collected the assignment and then went over each part of the problem getting the answers 15.6 seconds, 2350 meters, and 1200 meters respectively. He used equations four and one for the first two problems respectively from the kinematics section of the equations sheet. Following his explanation Manning went over the first woolly problem of the woolly mammoth packet, and instructed the class to finish the packet for homework. The answers for question one are 20 seconds and 11 m/s for parts ‘A’ and ‘B’.
