Acceleration of blood pumped by heart

  1. Jun 5, 2008 #1
    Hey,
    I"m having a few problems with some motion problems and was wondering if someone could help?

    The left ventricle of the heart accelerated blood from rest to a velocity of +23.9 cm s-1. If the displacement of the blood during the acceleration is +1.80 cm, determine its acceleration (in cm s-2).

    Welcome to PF!

    Hi melinaamos ! Welcome to PF! :smile:

    vi = 0, vf = 23.9, x = 1.8.

    (btw, you should have used the standard form for homework questions)

    Hint: what equations do you know relating vi, vf, x and t? :smile:

    Hi melinaamos! :smile:

    Well, that's the right formula.

    Show us your working, so we can check it.

    (Sometimes the book is wrong! :rolleyes: )
