3 balls are launched off a tall cliff with the same initial velocity

  1. Oct 31, 2009 #1
    which will strike the ball at the fastest speed?
    -one launched upward at a certain angel
    -one launched downward
    -one launched perfectly horizontally




    I am guessing 1, since it has the additional height to fall under gravity influence

    What ball and where is it?

    One of the balls is launched horizontally from a cliff.
    One of the balls is launched downward from a cliff.
    One of the balls is launched upward from a cliff.

    Yea, three balls are launched...but you are asking which ball would "strike the ball at the fastest speed"? Clearly there is another ball/target that these three balls are aimed at?

    Which has the highest speed right before hitting the ground

    i misstyped. it should be which of these 3 balls strikes the ground with the greatest speed.

    Instead of guessing, why not try writing out the kinematic equations for each scenario. (You will get a most interesting result)
