Asked by Colin

I know how to get the speed if it accelerated the whole time. How do I calculate the cruising speed?

Starting from rest, a car travels 1,350 meters in 1 min. It accelerated at 1 m/s^2 until it reached its cruising speed. Then it drove the remaining distance at constant velocity

Thanks

The cruising speed in this case is the speed attained after the 1 min of acceleration. Call it V. The average speed during accleration is V/2.
(V/2)*(60 s) = 1350 m
V = 45 m/s
