You are designing a roller coaster for a new amusement park on the Moon. You envision a loop with a radius of 55 meters in your track. (a) What minimum speed at the top will a car have to possess in order to successfully negotiate the loop? The gravitational acceleration on the Moon is 1.6 m/s2. (b) What speed at the top of the loop would a car need to have if the same roller coaster was built on Earth?
