Power!

[alfmaniac]

Okay, I am going crazy over this one! An automobile engine develops a torque of 280 Nm at 3800 rpm. What is the power in watts and in horsepower?

I have converted the 3800 rpm to 63.3 rev/sec and I know that power is equal to work over time but I am not sure how to figure out work and there is no specific time given. Any hints or tips?!?! Please!! :cry:

Here's a hint: Work in a rotating system is torque times angle turned.
