Answer:

Centripetal acceleration of boy on a string is 47.02 m/s²

Explanation:

It is given that,

Radius of the circle, r = 1.8 m

Speed of the ball, v = 9.2 m/s

Centripetal acceleration is given by :

a_c=\dfrac{v^2}{r}

a_c=\dfrac{(9.2)^2}{1.8}

a_c=47.02\ m/s^2

Hence, the centripetal acceleration of a ball on a string that is whirled horizontally over a boy’s head is 47.02 m/s²
