Transcribed Image Text:(1) An observer watching a rotating wheel notices that it turns through 80.0 rad in the first 5.0
sec, and through 25.0 rad in the next 2.5 sec. The wheel appears to have a constant
angular acceleration a. Find the value of a, the initial angular velocity mo, the angular
velocity at 5.0 sec (w1), and the angular velocity at the end of the process (o2).
Answers: a = -1.60 rad/sec?, wo = 20.0rad/sec, o 12.0 rad/sec, o2 = 8.0rad/sec
murement nark is turning at a rate wo, and accelerating at a rate
