5.57 • Stay Dry! You tie a cord to a pail of water and swing the pail in a vertical circle of radius 0.600 m. What minimum speed must you give the pail at the highest point of the circle to avoid spilling water?

The minimum speed of pail is 2.42 m/s.

Explanation:

Given that,

Radius = 0.600 m

We need to calculate the minimum speed of pail

Using centripetal force

Where, v = speed

r = radius

g = acceleration due to gravity

Put the value into the formula

Hence, The minimum speed of pail is 2.42 m/s.
