A car is traveling along a road and its engine is turning, Ask an Expert

Academics

A car is traveling along a road, and its engine is turning over with an angular velocity of +190 rad/s. The driver steps on the accelerator, and in a time of 7.0 s the angular velocity increases to +300 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 +190 rad/s during the entire 7.0-s interval?

(b) What would have been the angular displacement if the angular velocity had been equal to its final value of +300 rad/s during the entire 7.0-s interval?
