Question

A bus slows down uniformly from 21 m/s to a complete stop in 21 seconds. How far did the bus travel before stopping?

Answer 1

`velocity_(final)-velocity_(initial)=(distance)/(time)\\\\ v_(initial)=21(m)/(s)\\ v_(final)=0(m)/(s)\\ time=21s\\\\ \Delta v *time=distance\\\\ distance=|(0-21)*21|=441m \\\\Bus\ traveled\ 441meters.`
