Determine the angular velocity if 2.5 revolutions are completed in 10 seconds. Round to the nearest tenth.

Va = 2.5rev/10s. * 6.28rad/rev = 15.7 rad/s.

correction: 2.5rev/10s * 6.28rad/rev = 1.57 rad/s.

To determine the angular velocity, we need to know the formula:

Angular velocity (ω) = (Number of revolutions completed / Time taken)

Given that 2.5 revolutions are completed in 10 seconds, we can substitute these values into the formula:

Angular velocity (ω) = 2.5 revolutions / 10 seconds

Simplifying this, we get:

Angular velocity (ω) = 0.25 revolutions per second

Rounding this to the nearest tenth, the angular velocity is approximately 0.3 revolutions per second.
