A grindstone of radius 4.0m is initialy spinning with an angular speed of 8.0 rad/s. The angular speed is the increased to 10rad/s over the next 4.0 seconds. Assume that the angular acceleration is constant. What is the average angular speed of the grindstone?

2. Relevant equations

Please check work.....

3. The attempt at a solution

avg w= (delta theta)/delta T

= (10 rad/s - 8 rad/s) / (4 s-0)

= .5 rad/s

Vt= r * avg w

= 4m * .5 rad/s

= 2 rad/s
