Asked by Rebecca

A car with good tires on a dry road can decelerate at about 5.00m/s^2 when braking. If the car is traveling at 34.0m/s, how long does it take the car to stop under these conditions?

Not quite sure if this is the correct procedure, but what I would have done is use the formula:
a=[delta]v/t since we are given a and t.
so 5=34/t and I got t=6.8s.
Where did you find this question? Just out of curiosity.

Vf=Vi+at

solve for time t.

**Havanna**The question was from a test that I had taken and I had gotten it wrong--I was just curious on which equation to use. And it turns out to be as simple as I thought it might be. Thank you both for your help!
