Energy required to accelerate a mass

  1. Nov 30, 2008 #1
    1. The problem statement, all variables and given/known data
    1-Calculate the energy (1/2 mv^2) for each of the following:
    a) a nova outburst that accelerate a mass of 1E-5 M_sun to
    a velocity of 1000 km/s


    2. Relevant equations
    1/2 mv^2


    3. The attempt at a solution

    Now, heres what Im unsure of. Do I just take the kinetic energy, or, do I have to do some strange integral? I'm still not very comfortable with integration and am unsure of when to use it.

    I'd say just take the kinetic energy as asked.
