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

[vijaym801]

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?

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)
