What minimum speed must a roller coaster have to make it around inside a loop without losing contact with the track? 9.9 m/s Thus the rider must be traveling at least 9.9 m/s to make it around the loop. How do you calculate minimum speed? Explanation: The minimum or critical speed is given by vcritical=√rg . This is the point where the normal (or tension, frictional, etc.) force is 0 and the only thing keeping the object in (circular) motion is the force of gravity. How do you find the minimum velocity of a loop? Thus we have found the...
