At what minimum speed must a roller coaster be traveling when upside down at the top of a circle if the passengers are not to fall out? Assume a radius of curvature of 9.2 m. m/s
-
Providing the passengers feel a centripetal acceleration (v² / r) greater .. or at least equal to the free-fall acceleration (9.80 m/s²) they will remain in their seats when upside down.
Find the minimum speed makes the centripetal accel. = 9.80 m/s²
v² /r = 9.80
v² = r x 9.80 .. .. v² = 9.20m x 9.80 = 90.16 ... .. .. ►v = 9.50 m/s
