Rollercoaster Madness B Assume there is no friction or air resistance Note: Track is not to scale, determine values based on given information. Use g = 10 m/s2 D C F A 8. Mark the location on the last hill where the car will reach. This is point G. Use g = 10 m/s2 E 1. Since there is no friction, what can be said about the total energy of the car at all points after A? 2. What is the mass of the cart? 3. Which point has the highest PE? 4. Which point has the highest KE? 5. Which point has PE = KE? 6. How much work did the motor put into the rollercoaster car? 7. If the motor is able to pull the car up in a time of 5 seconds, what is the power rating on the motor? Fill in ALL blank boxes. A B Total E (joules) 0 100. PE (joules) 0 100. KE (joules) 0 0 Velocity (m/s) 0 Height (m) 0 C D 20.0 E F -20.0 50.0 9.5 10.0 G
