At time t=0 a grinding wheel has an angular velocity of 24.0 rad/s. It has a constant angular acceleration of 35.0 rad/s^2 until a circuit breaker trips at time t= 2.50 s. From then on, the wheel turns through an angle of 440 rad as it coasts to a stop at constant angular deceleration. a.) Through what total angle did the wheel turn between t= 0 and the time it stopped? answer in radb.) At what time does the wheel stop? (secs)c.)What was the wheel's angular acceleration as it slowed down?Express your answer in radians per second per second.

a) , b) , c)

Explanation:

a) The final angular speed at the end of the acceleration stage is:

The angular deceleration is:

The change in angular position during the acceleration stage is:

Finally, the total change in angular position is:

b) The time interval of the deceleration interval is:

The time required for the grinding wheel to stop is:

c) The angular deceleration of the grinding wheel is:

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
