Homework Help: Simple problem

  1. Mar 5, 2007 #1
    1. The problem statement, all variables and given/known data
    What is the power of a machine that does 1800 N-m of work per minute?


    2. Relevant equations
    KE = m*v^2/2

    V = sqrt(2KE/m)


    3. The attempt at a solution
    I don't know what N-m are... so I'm not sure what to do..

    N-m is better known as Joules (energy, work) and not to be confused with Torque which has the same dimensions. Work/time is power.
