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.
