## Homework Statement

So I am calculating torque and power for a disk of radius 0.5 m that is subjected to a force of 50 N at its periphery and is rotating at angular velocity of 100 rad/s. Find torque and power.[/B]

## Homework Equations

**Torque= radius x Force = 0.5m *50N = 25Nm**

Power= dW/dt= F*w(omega)= 25Nm * 100 rad/sec .... WHy the solutions book has an answer 2500 Nm/s. Why did they ignore the radians. I was thinking to convert the radians into meters or something like that. What am I not understanding here?
