Question

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?

Answer 1

The minimum speed of pail is 2.42 m/s.

Step-by-step explanation:

Given that,

Radius = 0.600 m

We need to calculate the minimum speed of pail

Using centripetal force

`F=(mv^2)/(r)`

`mg=(mv^2)/(r)`

`v=√(gr)`

Where, v = speed

r = radius

g = acceleration due to gravity

Put the value into the formula

`v =√(0.600*9.8)`

`v=2.42\ m/s`

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