At t=0 a grinding wheel has an angular velocity of 21. 0 rad/s. It has a constant angular acceleration of 26. 0 rad/s2 until a circuit breaker trips at time t = 2. 10 s. From then on, it turns through an angle 438 rad as it coasts to a stop at constant angular acceleration. Through what total angle did the wheel turn between t=0 and the time it stopped?

The tips of the blades on Turbine A are moving twice as fast as the tips of the blades on Turbine B. Part D Which turbine takes the lesser amount of time to rotate through 1.0 radian of angular displacement? A. turbine A a turbine B They take the same amount of time. The answer cannot be determined from the information given. ; Subrnit Request Answer Part 5 29 As in Part D, two wind turbines with different length blades are rotating. Consider what needs to happen in order to change the angular speed of one of the turbines. If the turbine is to spin more quickly, should the angular acceleration, a be positive or negative?B. a should be positive.C. a should be negative. D. We cannot tell which direction a should be without knowing the direction of the angular velocity,
