Find the velocity in rad/sec if the wheel is completing:
1. 500 rev/sec
2. 300 rev/sec

## Answers (1) 2021-02-12
To convert, remember that
1 rev $$\displaystyle={2}\times\pi$$ rad
Substitute:
1. $$\displaystyle{500}\times{2}\pi={1000}\pi$$
$$\displaystyle\approx{3141.6}$$ rad/sec
2. $$\displaystyle{300}\times{2}\pi={600}\pi$$
$$\displaystyle\approx{1884}$$ rad/sec
