A roller coaster ride includes a circular loop-the-loop. The roller coaster carriage enters the bottom of the loop at 25m/s. The loop has a diameter of 30mThe carriage is free-wheeling along the track meaning that it is not being driven by a motor. What is the speed of the carriage at the top of the loop?
