Question

If an object in circular motion has angular speed ω = 2 rad/s and radius r = 3 m, what is its linear speed?

Options

• v = 6 m/s

• v = 1.5 m/s

• v = 3 m/s

• v = 2/3 m/s

Answer 1

v = 6 m/s

Explanation:

Using the relationship v = rω, we get v = 3 × 2 = 6 m/s. Linear speed increases with both radius and angular speed.
