  1. The Corkscrew By: Amanda Hui & Jessica Lu

  2. Question #1 • A 400.-kg roller coaster is at the top of a 48.0m hill. At the bottom of the hill the roller coaster is going 24.5m/s. The density of air is 1.2250 kg/m3 and the cross sectional area of the coaster is 2.50m2. If the drag coefficient for the coaster is 0.850, find: a) The drag force of the coaster at the bottom. b) Assuming drag force is constant down the hill, find the angle of inclination of the hill. 24.5m/s 48.0m 400-kg

  3. Question #2 7.50m/s • A roller coaster has two vertical loops one after the other. The roller coaster has a speed of 7.50m/s at the top of the first loop with a height of 25.8m. It then proceeds around the second vertical loop with a height of 16.0m. What is the speed of the roller coaster at the top of the second vertical loop? (Assuming no friction.)
