I am stuck on this problem, its multiple choice and I can get 3 of the 5 choices :(
Here's the problem if anyone is interested....
Assume that the brakes of your car can slow it with an acceleration of magnitude 6 m/s2. If Homer steps onto the road 50 m in front of your car, what is the maximum speed you could be going in order to avoid hitting Homer? Assume that it takes you 0.5 s to hit the brakes and that you have constant acceleration during braking.
