1. The problem statement, all variables and given/known data

The question provides three equations:

Work = Torque x Angle (angle must be in radians).
Power = Work/Time.
As for linear measures, power can also be calculated as Power = Torque x Angular Velocity (where velocity is in rad/s).

Using the data given, calculate the Power produced by the Quads at an angular velocity of 180 degrees/s. Give your answer to the nearest whole number (no decimal) and DO NOT include the units.

Data: at 180 degres/s, quad torque = 118 Nm.

2. Relevant equations

Power = Torque x Angular Velocity
P = T x w

3. The attempt at a solution

Power = Torque x Angular Velocity
P = T x w
P = 118 x 180 degrees/s.
P = 21 240.

The correct units for power in SI are 1 Nm/s = 1 W

Sorry of course it's Watts!

Does the working out/answer look appropriate?
