PHYSICS 11-30-11 Power & the Horsepower Lab

PHYSICS: Great job on the horsepower lab. Lotta noise – I’m thinking some of you took out some of your physics phrustrations on the stairs! Post your own horsepower numbers here. Did you notice that not all of the stairs are the same height? BTW: 1 Hp = 746 W and 1 kg = 2.2 lb. Post your lab results here. Who has the most power? And why?

Here’s the lecture from today on power. Great start on the problems!
