# An object with a mass of 15 kg is revolving around a point at a distance of 1 7m. If the object is making revolutions at a frequency of 12 Hz, what is the centripetal force acting on the object?

${F}_{C} = 127.03 N$

#### Explanation:

So from the question:

Given:

$m = 15 k g$
$r = 17 m$
$v = 12 H z$

We know:

${F}_{C} = m {v}^{2} / r$

${F}_{C} = 15 \cdot {12}^{2} / 17$

${F}_{C} = 15 \cdot \frac{144}{17}$

${F}_{C} = \frac{2160}{17}$

${F}_{C} = 127.03 N$
