2. An object is spun in a circle of radius 0.4 m with a frequency of 8.0 Hz. What is its velocity? Formula V= r= fequiv

Here's how to calculate the velocity of the object:<br /><br />**Formula:**<br /><br />* v = 2πrf<br /><br />**Where:**<br /><br />* v = velocity (m/s)<br />* r = radius (m)<br />* f = frequency (Hz)<br /><br />**Given:**<br /><br />* r = 0.4 m<br />* f = 8.0 Hz<br /><br />**Calculation:**<br /><br />v = 2 * π * 0.4 m * 8.0 Hz<br />v = 20.1 m/s (approximately)<br /><br />**Answer:**<br /><br />The velocity of the object is approximately 20.1 m/s.<br />
