Question

Carlos operates a helicopter. Carlos decides to measure the rotational velocity of the helicopter blades.
What would be an appropriate unit for Carlos's purpose?

Answer 1

radians per second

In general, angular velocity is measured in angle per unit time, e.g. radians per second. The SI unit of angular velocity is expressed as radians/sec with the radian having a dimensionless value of unity, thus the SI units of angular velocity are listed as 1/sec.

Answer 2

Answer:

Given that Carlos operates a helicopter. Carlos decides to measure the rotational velocity of the helicopter blades. we have to find the appropriate unit for Carlos's purpose.

The angular velocity ω is the rate of change of angle with respect to time,

Angle measure in radians or degrees and time in second.

Hence, the appropriate unit for Carlos's purpose is degrees per second.
