Height with Velocity Question

  1. Jan 16, 2012 #1
    1. The problem statement, all variables and given/known data

    If you toss your little cousin straight up into the air at 5 m/s, how high above your hands will he/she go?


    0.5 m

    1.3 m

    2.0 m

    70 m


    2. Relevant equations

    d = (0-5^2) / 2 (-9.8)
    d = 1.3 m

    3. The attempt at a solution

    My cousin will fly 1.3 m high if I throw her at 5 m/s.

    Is that correct?

    Distance = ??
    Tine = ??
    Velocity initial=5m/s
    Velocity final = 0m/s
    Acceleration = -9.8m/s

    T = Vf-Vi / A
    T = -5 / -9.8
    T = .51s

    D = ViT + AT^2 / 2
    D = (5)(.51) + ((-9.8)(.51)(.51) / 2)
    D = 1.3

    yes 1.3 is correct
