What is the centripetal acceleration of a ball on a string that is whirled horizontally over a boy’s head? The radius of the circle is 1.8 meters, and the ball is traveling at 9.2 meters/second.

Respuesta :

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 :

[tex]a_c=\dfrac{v^2}{r}[/tex]

[tex]a_c=\dfrac{(9.2)^2}{1.8}[/tex]

[tex]a_c=47.02\ m/s^2[/tex]

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