11 10 points A Do C B hA hc hB D A toy car track is set up as shown in the diagram above, where: hA = 5.20m hB = 3.80 m hc = 4.60 m The radius of the loop is 0.700 m. If the toy car has a mass of 0.720 kg and is released from rest at point A, then calculate: a. The total energy of the car. b. The gravitational potential energy of the car at point B. c. The kinetic energy of the car at point B. d. The speed of the car at the top of the loop (point C). e. The normal force at the top of the loop (point C)
