Question

What is the anvulat velocity of flying wheel making 300 rpm in rad / sec ?

Answer 1

The conversion between radians and revolutions is 2πrad=1rev. The conversion between seconds and minutes is 60s=1min. Using these two conversion factors, we can convert it into \text{rad/s}:

813.0revmin⋅2πrad1rev⋅1min60s=85.14rad/s (4 s.f.)
