Answer:

a = 16 m/s²

Explanation:

The mass of the object, m = 200 kg

The radius of the circular motion, r = 4 m

The speed of the object, v = 18 m/s

The centripetal acceleration is given by the relation,

                               a = v²/r

Substituting the given values,

                               a = 18 / 4

                                  = 16 m/s²

Hence, the centripetal acceleration of the object is, a = 16 m/s²
