Centripetal acceleration: radius 23.09 m, speed 11.42 m/s
An object moves in a circle of radius 23.09 m at constant speed 11.42 m/s. The centripetal acceleration has magnitude a_c = v² / r = 5.644 m/s² and is directed toward the center of the circle. The corresponding centripetal force is supplied by whatever agent constrains the motion (tension, gravity, friction, etc.).
a_c = v^2 / r; F_c = m v^2 / r
