Xcelerator is a rollercoaster in Knott's Berry Farm. The rollercoaster train is launched from the station at an initial speed v, curves 90° vertically upwards to reach a maximum height of 60 m above the station, and then returns to the ground in an equally graceful manner. (a) Find the minimum launch speed v needed for the train to reach the maximum height. (b) The head engineer advises you to not launch the train at this minimum speed, and you both agree to set the initial speed to v = 36.7 m/s. What is the speed of the train as it reaches the maximum height? Xcelerator is a rollercoaster in Knott's Berry Farm.
