Acceleration question.

  1. Mar 2, 2013 #1
    Gday mates,

    Here is my question.

    A police car is stationery when a speeding car drives past at 41.66m/s, if it takes the police car 1.5 seconds to react and the police car accelerates at a rate of 12m/s/s then how long will it take until the police car catches the bad guy and how far will the police car have driven?

    Yea it is a hard one

    Cheers :)

    Maybe you didn't read the rules of the forum. For homework problems you have show that you have at least given some thought to the problem and make an attempt. If you don't do that a moderator will delete this post soon.

    ... and don't forget to post any equations you suspect will be relevant.

    Like others have said you need to follow the rules and post homework questions in the correct format, thats why when you make a post there is 3 sections to fill out.
    But I answered a question that is pretty much exactly the same as yours just recently, but with a different set of values and worded with a different situation in the word problem

    this should get you started on how to solve this problem.

    Thanks for that, I didn't know about this three section thing...
