Homework Statement



You lift a 40 kg weight vertically 2 meters in 2 seconds. Your power output is ____.

Homework Equations





The Attempt at a Solution



M = 40 kg
A = 1 m/s
F = ?

I have no idea how to go further than this. Also, what is power abbreviated as? For example, force is abbreviated as F and mass is M. Momentum is P, but what is power?

Power is just energy / time.

Power is generally 'P' and so gets confused with momentum 'p'.

Power is work/time

But before you go too far here, what is that A supposed to be?
 
Thanks! I got the answer I couldn't figure out what the equatio nfor power was.
