Here's the problem: "A motorist is traveling at 18.0 m/s when he sees a deer in the road 38.0 miles ahead. If the maximum negative acceleration of the vehicle is -4.5 m/s, what is the maximum reaction time (delta)t of the motorist that will allow him to avoid hitting the deer?

Now when I do my calculations, I get:
vi = 18.0 m/s
vf = ?
t = ?
a = -4.5 m/s^2
d = 38.0 m

d = vit + 1/2at^2
38.0 = 18t + (-2.25)t^2
2.25t^2 - 18t + 38.0 = 0

Then put into quadratic formula....which gives out a negative root...
So doesn't that mean the driver can't avoid hitting the deer?

Here is todays brain stretcher on the subject of Chemistry:

Which element is the most common in the normal Human body

As always, fastest fingers first, the only trick is it needs thought, but it gives you something to do in the AM.
