Answer:2.88 m/s
Step-by-step explanation:
Given
radius of circle r=0.85 m
At highest Point weight will Provide the centripetal Force
thus
[tex]weight=mg[/tex]
[tex]Centripetal\ Force=\frac{mv^2}{r}[/tex]
where m is the mass of water in bucket
[tex]mg=\frac{mv^2}{r}[/tex]
[tex]v=\sqrt{gr}[/tex]
[tex]v=\sqrt{9.8\times 0.85}[/tex]
[tex]v=2.88 m/s[/tex]
