Given,
Mass of the ball, m=5 kg
Radius of the ball, r=3 m
Speed of the ball, v=7 m/s.
To find
The centripetal acceleration
Explanation
The centripretal force is given by
[tex]F=\frac{mv^2}{r}[/tex]Putting the values
[tex]F=5\times\frac{7^2}{3}=81.66\text{ N}[/tex]Conclusion
The centripetal acceleration is 81.66 N
