Hammer thrower - Angular acceleration

  1. Oct 28, 2004 #1
    A hammer thrower accelerates the hammer (mass = 7.3 kg) from rest within four full turns (revolutions) and releases it at a speed of 27.2 m/s. Assuming a uniform rate of increase in angular velocity and a radius of 2.0 m, calculate (a) the angular acceleration, (b) the (linear) tangential acceleration, (c) the centripetal acceleration just before release, (d) the net force exerted on the hammer by the athlete just before release, and (e) the angle of this force with respect to the radius of the circular motion. Neglect the effect of gravity.

    I know that angular acceleration is w(omega)/t, but I can't figure out how to find t...
