Spinning Dragonflies Measurements show that when a dragonfly does a spin-dry (Problem 49), it can spin up

Question:

Spinning Dragonflies Measurements show that when a dragonfly does a "spin-dry" (Problem 49), it can "spin up" from v0 = 0 to v = 104 rad/s in 0.250 s.

(a) Assuming constant angular acceleration, how many revolutions does the dragonfly make in this time?

(b) How many revolutions has the dragonfly made when its angular speed is 51.2 rad/s?
