Rotational kinematics

  1. Jun 21, 2005 #1
    I am unsure of how to do this problem. I know that the angular velocity=change in theta/change in time but don't know how to get the # of revolutions?

    At the local swimming hole, a favorite trick is to run horizontally off a cliff that is 6.2 m above the water. One diver runs off the edge of the cliff, tucks into a "ball," and rotates on the way down with an average angular speed of 1.2 rev/s. Ignore air resistance and determine the number of revolutions she makes while on the way down

    Well if you solve for the time it takes the diver to reach the water, can't you just multiply that by 1.2 rev/sec to get # of revolutions?
