At time t=0 a grinding wheel has an angular velocity of 26.0 rad/s . it has a constant angular acceleration of 30.0 rad/s2 until a circuit breaker trips at time t = 2.20 s . from then on, the wheel turns through an angle of 440 rad as it coasts to a stop at constant angular deceleration. through what total angle did the wheel turn between t=0 and the time it stopped? express your answer in radians. at what time does the wheel stop? express your answer in seconds. what was the wheel's angular acceleration as it slowed down? express your answer in radians per second per second.

Imagine you work as a consultant, and your daily job involves listening to the constructive criticism of others. as part of your job, you must listen to opposing viewpoints to make important decisions. in this activity, you are a consulting dam engineer. you must make a decision about four different dams; should they be repaired, taken down, or left alone? you will listen to contrasting opinions about what should be done with the dams before you make the final decision. as the consulting dam engineer, what do you decide to do with this dam? explain your reasoning. by making your decision, did you support the opinions of the mayor and/or the dam safety official? why or why not?
