Homework Help: Kinematics hwk problem

  1. Feb 2, 2005 #1
    Can someone tell me if I solved this problem correctly?

    The left ventricle of the heart accelerates blood from rest to a velocity of +22 cm/s.
    (a) If the displacement of the blood during the acceleration is +1.7 cm, determine its acceleration (in cm/s2).
    142.353 cm/s2
    (b) How much time does it take for the blood to reach its final velocity?
    0.155 s

    For a, I used the equation v final^2= v initial^2 + 2a(displacement)
    vfinal=22cm/s
    vinitial=0
    displacement=1.7cm


    For b, I used the equation v final= v initial + a*t
