The centripetal acceleration must equal the acceleration due to gravity to keep the car from falling:

v2r=gthe fraction with numerator v squared and denominator r end-fraction equals g 3. Solve for velocity Rearrange the formula to solve for v=g⋅rv equals the square root of g center dot r end-root a-roller-coaster-has-a-vertical-loop-with-radius-of-15m

, the car must maintain a speed where the centripetal force at the top of the loop is at least equal to the force of gravity. The minimum speed is approximately (or about 1. Identify physical constants The centripetal acceleration must equal the acceleration due
