            Make it step by step under my instructions. 


(1)  First calculate the linear speed by dividing the distance by time.


     The distance is one circumference  taken 10 times (10 revolutions) in 29.3 seconds,

     so the speed is  v =   meters per second.




(2)  Then apply the formula

         a =   

     to find the centripetal acceleration in m/s^2.



(3)  Finally, to find the force, multiply the centripetal acceleration by the mass.


    You will get the force in Newtons.


Happy calculations !
