The frequency of revolution of a point in a circle is 20 s-1, the radius of a circle is 16 cm. Determine the centripetal acceleration of a point.
To calculate the value of the centripetal acceleration of the presented point, we will use the formula: ac = 4 * Π ^ 2 * ν ^ 2 * R.
The values of the variables: ν is the frequency of rotation of the specified point along the circumference (ν = 20 s-1); R is the radius of the circle (R = 16 cm = 0.16 m).
Calculation: ac = 4 * Π ^ 2 * ν ^ 2 * R = 4 * 3.14 ^ 2 * 20 ^ 2 * 0.16 = 2524 m / s2.
Answer: The centripetal acceleration of the presented point is 2524 m / s2.
