Respuesta :
The velocity of the ball is 12.5 m/s
Explanation:
The velocity of the ball is given by the ratio between the distance covered by the ball and the time taken:
[tex]v=\frac{d}{t}[/tex]
First, we calculate the distance covered. We know that the radius of the circle is
r = 0.450 m
And the length of the circumference is
[tex]L=2\pi r = 2\pi(0.750)=4.7 m[/tex]
The ball makes 25.0 revolutions, so a total distance of
[tex]d=(25.0)L=(25.0)(4.7)=117.5 m[/tex]
In a time of
t = 9.37 s
So, its velocity is
[tex]v=\frac{117.5}{9.37}=12.5 m/s[/tex]
