Homework Help: Solar Wind and Kinetic Energy

  1. Mar 2, 2014 #1
    1. The problem statement, all variables and given/known data
    At what rate does the solar wind carry kinetic energy away from the sun? Give your result first in watts, then as a fraction of the Sun's luminosity in photons, L=3.8*10^26 W

    2. Relevant equations
    mass loss of sun- Msunloss=4πr2

    3. The attempt at a solution
    I think this is one of those problems that seems so simple I am second guessing myself. Is it really as simple as input the mass loss of the sun in for my m in the KE formula and then dividing it by a second to find the wattage and then converting into luminosity?

    If you know v and ρ: yes.
