Rotation rate

  1. Oct 8, 2013 #1
    1. The problem statement, all variables and given/known data



    A diver jumps from a 13m high tower, and hopes to complete 212 somersaults.
    what should be the rotation rate be

    2. Relevant equations



    3. The attempt at a solution

    13 m = (1/2)(9.81 m/s²)(t²)
    t = 1.628 s

    ω = 2.5 rev / 1.628 s
    ω = 1.53 rev/s I'm still getting this wrong

    Am I not using the correct equation for time?

    Please post the problem statement so we can figure out what it is you're trying to figure out!

    Ugh...Nevermind i figured it out. I needed ot find the Rotation in radians and divided it by the time.
