Answer:

Acceleration will 7.5 times g = 7.5 g

Explanation:

Centripetal acceleration is given by a = v²/r.

The speed in m/s will be; (96.6 Km/h )÷ 3.6

                                        = 26.83 m/s.

Centripetal force = v²/r

                            = 26.83²/9.80

                            = 73.454 m/s²

But; g = 9.8 m/s²

Therefore the acceleration in terms of g will be;

  = 73.454/9.8

   = 7.5 g

Acceleration is 7.5 g
