A car is moving east at 35 m/s. If it accelerates at 20 m/s² for a period of 22 seconds, what is its final velocity?

The final velocity of the car after accelerating for 22 seconds at 20 m/s², starting from an initial velocity of 35 m/s, is 475 m/s. This is calculated by using the relation between acceleration, initial velocity, and time. Thus, the car speeds up significantly over the period.
