    Acceleration Due to gravity!
    If we were conducting an experiment on calculating the acceleration due to gravity by droping a stone from a specific hight and if by any suitable means, the stone was given an initial downward push instead of just being released, what effect would it have on the calculated value of "g"?

    Suppose that a speeding car goes by at twice the speed limit of 45 mph. how long will it take for a police car (starting from rest) that experiences a constant horizontal acceleration of 1.5 g's to catch up to the speeder

    You should have started your own thread. For your information, use and and solve for t, the time. Since both distances are the same, equate both equations.
