The total mass of a rollercoaster is 650 kg. Use the measurments in the image and your knowledge of conservation of energy to answer the following questions: 1) Use the law of conservation to find the speed of the rollercoaster at point B 2) If it takes the motor 20.0 s to pull the rollercoaster to point A, fing the power of the motor. 3) In real life, some of the energy the roller coaster has at point A will be lost as thermal energy due to friction as it travels through the track. If the speed of the roller coaster at point C is only 19 m/s, calculate the amount of energy that was lost due to friction
