A wheel has an angular speed of 85 rev/s when it experiences a constant angular acceleration of 100 rev/s2 which causes it to spin FASTER. During this time the wheel completes 26 rev. Determine how long the wheel was experiencing this angular acceleration.

Answer 1

100 t^2 + 85 t = 26 ... 100 t^2 + 85 t - 26 = 0

use the quadratic formula to find t
