To find the minimum speed required for a roller coaster to successfully complete a vertical loop with a radius of

At the top of the loop, two main forces are at play: gravity ( a-roller-coaster-has-a-vertical-loop-with-radius-of-15m

) and the normal force from the track. For the "minimum" speed (the point where the car just stays on the track), the normal force is zero. We use: ≈is approximately equal to 2. Set up the equation To find the minimum speed required for a

, 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 a-roller-coaster-has-a-vertical-loop-with-radius-of-15m
