While driving her new Camaro at 20.0 m/s down a four-lane highway, Jessica comes up behind a slow-moving dump truck and decides to pass in the left-hand lane. If Jessica can accelerate at a rate of 5.0 m/s^2, how long will it take for her to reach a speed of 30.0 m/s? plz help asap many thanks :)
So she needs to increase her speed by 10 m/s and each second her speed increases by 5 m/s, so....
use v=u + at where v= final velocity = 30, u= initial velocity = 20 , a= acceleration = 5 find out t ,which is required.....
