Extra Credit 2

Today we did our egg drop competition. If the height that you dropped your egg was 15.7 m, how fast was the egg moving when it hit the floor? What was the momentum of just the egg?  mass of an egg= 50.0 g. Post your answer by end of school on Thursday.

    Vf+17.55m/s

    p=875 kgm/s

    sorry, the first equation is supposed to be this

    Vf=17.5 m/s

    gotta love typeos

    Vf = sqrt[2(9.81)(15.7)] = 17.6 m/s

    P = (0.050)(17.6) = 0.88 kg•m/s

    The upper comment was mine.
    I didn't realize it has Anonymous instead of my name on it...

    the velocity of the egg when it hit the floor was 17.6 m/s

    the momentum of the egg was 0.88 kgm/s

    g=-9.81 m/s^2
    h= 15.7 m
    Vf^2=-2gh
    Vf=sqrt[-2(-9.81)(15.7)]
    Vf=17.6 m/s

    p=mv
    m=0.0500 kg
    v=17.6 m/s
    p=(0.0500)(17.6)=0.880 kg*m/s
