v = speed of the object moving in circle = 11.40 m/s
r = radius of the circle in which the object move = 5.52 m
a = centripetal acceleration of the object moving in circle
centripetal acceleration is given as
a = v²/r
where a = centripetal acceleration
v = linear speed of the object
r = radius of the circle
inserting the values
a = (11.40)²/5.52
a = 129.96/5.52
a = 23.5 m/s²
