A girl throws a slingshot pellet directly at a target that is far enough away to take 0.9 s to reach. How far below the target does the pellet hit?

How high above the target should she aim?

    How far does anything fall in 0.9 s ??

    -(1/2)(9.8) t^2 = - 4.9(.81) = - 3.97 m

  • physics -

    Of course, if she's throwing it upwards, it's going to rise for .45 sec and then fall for .45 sec.

    How far above the target she will aim depends on how far away the target is. It will also affect how hard she has to throw it.
