A car is traveling along a road, and its engine is turning overwith an angular velocity of +209 rad/s. The driver steps on theaccelerator, and in a time of 15.9 s the angular velocity increasesto +300 rad/s. (a) What would have been the angular displacement ofthe engine if its angular velocity had remained constant at theinitial value of +209 rad/s during the entire 15.9-s interval? (b)What would have been the angular displacement if the angularvelocity had been equal to its final value of +300 rad/s during theentire 15.9-s interval? (c) Determine the actual value of theangular displacement during the 15.9-s interval.
(a) ? = ? rad
(b) ? = ? rad
(c) ? = ? rad
