Question

you swing a 4.7-kg bucket of water in a vertical cicle of the radius 3.2m. What spped must the bucket have if it is to complete the circle

Answer 1

the bucket must have a speed \[v \ge \sqrt{gr}\]
g = gravitational acceleration
r= the radius of the circle
here g=9.8 m/s^2 and r=3.2m
\[v \ge 5.6 m/s\]
