Velocity, Time, and Distance Problem

  1. Apr 3, 2009 #1
    1. The problem statement, all variables and given/known data

    A bunny runs along a straight path at a constant velocity of 25 m/s [N] when it passes a sleeping groundhog who immediately beings to chase the bunny with a constant acceleration of 3.0 x 10^-3 m/s^2. How long before the bunny is caught by the groundhog? How far would the groundhog go before catching the bunny? what would be the groundhog's final speed? Is this reasonable?


    2. Relevant equations

    d=vt

    d=at^2/2

    Since they both equal d, they equal each other.

    vt=at^2/2

    3. The attempt at a solution

    I plugged in the numbers and came up with an answer of 16666.6 s. (Roughly 4 hrs 37 min)
    I'm just not sure if I'm doing this correctly...any tips or advice?

    Yup that's how to do that part of the problem. Notice the acceleration is amazingly slow and that is why it is going to take so long to catch up. With the time you can simply plug in to solve the rest of the problem.
