How to calculate average power?

  1. Jan 14, 2010 #1
    during a human heart beat, 20g of blood are pushed into the main arteries. This blood is accelerated from a speed of 0.2m/s to 0.34m/s. For a heart pushing at 70bpm, calculate the average power of the heart pump

    This appears as homework, and this is not the place, but power is the time rate of doing work.

    P = work/time = Fd/t = F v = Ma v
