First you multiply 199 with 14.2 to get a.
Then you multiply 263 with 14.2 to get b.
I haven't figured out c yet but i'll let you know!
Please Help. I am not sure how to set up or do this problem. Thanks
A car is traveling along a road, and its engine is turning over with an angular velocity of +199 rad/s. The driver steps on the accelerator, and in a time of 14.2 s the angular velocity increases to +263 rad/s.
(a) What would have been the angular displacement of the engine if its angular velocity had remained constant at the initial value of +199 rad/s during the entire 14.2-s interval?
(b) What would have been the angular displacement if the angular velocity had been equal to its final value of +263 rad/s during the entire 14.2-s interval?
(c) Determine the actual value of the angular displacement during the 14.2-s interval.

For c, you find the average of 199 and 263, then you multiply it by 14.2! Hope that helps!
