Homework Help: What is the power output?

  1. Nov 10, 2008 #1
    1. The problem statement, all variables and given/known data

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

    2. Relevant equations

    3. 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?
