The correct question is

A Ballat dancer does a pirouette on the tip of his toe if the dancer has a weight of 580 n and the tip of his ballot show measures 0.02 by 0.01 M what pressure does his to exert on the stage?

Solution

The area of the tip of the ballot show is equal to [tex]0.02 * 0.01 = 0.0002[/tex] square meter

Pressure is equal to force applied divided by the area of the contact point.

[tex]P = \frac{Force}{Area}[/tex]

Substituting the give values we get -

[tex]P = \frac{580}{0.0002} \\P = 2900000[/tex] Newton per square meter
