Answer: 14.28 m/s
Explanation:
Assuming the girl is spinning with <u>uniform circular motion</u>, her centripetal acceleration  is given by the following equation:
 is given by the following equation:  
 (1)
 (1)
Where:  
 is the <u>centripetal acceleration</u>
 is the <u>centripetal acceleration</u>
 is the<u> tangential speed</u>
 is the<u> tangential speed</u>
 is the <u>radius</u> of the circle
 is the <u>radius</u> of the circle
Isolating  from (1):
 from (1):
 (2)
 (2)
 
 
<u />
Finally:
 This is the girl's tangential speed
 This is the girl's tangential speed
 
        
             
        
        
        
Answer
Factors Affecting Acceleration Due to Gravity
  
(1) Position on the planetary surface, it is higher at the axis (poles),
(2) Mass of the planet, higher with planets of larger masses
(3) Distance between object and the centre of planet, the larger the distance, the smaller the acceleration due to gravity.
