I NEED HELP WITH THESE TWO QUESTIONS 1) you are riding a roller coaster. Your cart carried you up to 100 meter hill. Then the cart drives you quickly down to the bottom hill. It goes back up to the second hill. The mass of you and the cart is 200 N (not kg). A) the cart is only able to go up 90 Meters on the second hill. What can't it make it to 100 meters?B) your friend thinks that the coaster breaks the law of conservation of energy because it does not go up the same height. Is your friend right?

Question 15 (4 points) ) Listen You are riding a roller coaster. Your cart is carried up to the top of a 100-meter hill. Then, the cart drives quickly down to the bottom of a hill. It goes back up a second hill. The mass of you and the cart is 200kg. A) When in the ride is your gravitational potential energy the highest? What is your gravitational potential energy at this point? B) When in the ride would your kinetic potential energy be the highest? How do you know this
