A whetstone of radius 4.0 m initially rotates with an angular velocity of 19 rad/s. The angular velocity then increases to 43 rad/s for the next 39 seconds. Assume that the angular acceleration is constant. Through how many revolutions does the stone rotate during the 39- second interval? Give your answer to one decimal place.
