You swing a 2 kg ball around on a string. The radius of the circle the ball travels around is 2 m, and you give the ball a velocity of m/s. What is the centripetal force on the ball?

Respuesta :

Answer:

F = 9 N

Explanation:

We have,

Mass of a ball is 2 kg

The radius of the circle the ball travels around is 2 m

Let the velocity of the ball is 3 m/s

It is required to find the centripetal force on the ball. The force that is required to move an object in circular path is called centripetal force.

[tex]F=\dfrac{mv^2}{r}\\\\F=\dfrac{2\times (3)^2}{2}\\\\F=9\ N[/tex]

So, the centripetal force on the ball is 9 N.
