Explanation / Answer

   Centrifugalforce   Fc   =   m* v2 / r    Total force onseat   F   =   Fc   +   weight   =   m* v2 / r   +   m * g    Given   maximum valueof       F   =   3* m * g    =>   3 * m *g   =   m * 2702 /r   +   m * g    2 *9.8   =   2702 / r    minimum radius   r   =   2702/19.6   =   3719.39   m   =   3.71* 103   m
