A discus thrower accelerates a discus from rest to a speed of 25 m/s by whirling it though 1.25 rev. Assume the discus moves on the arc of a circle 1m in radius.
Determine the magnitude of the angular acceleration of the discus:
ω=angular velocity
ω=v/r=25m/s / 1m = 25rad/s
ω^2=2ad
(25rad/s)^2=2a1.5(pi2)
a=33m/s^2
is this correct?
