A soccer ball is kicked from the top of a 256 -foot building with an initial velocity of 6 ft/s. How far from the base of the building will the ball land?

Answer 1

They probably want you to do this by assuming that air resistance is negligible, although that is not a good bad assumption in this case.

Use the height of the building to determine how long it takes to fall.

Then multiply that time by the initial velocity (assumed horizontal) for the horizontal distance that it travels.

Answer 2

A soccer ball is kicked from the ground in an arc defined by the function,h(x) = -2x2 + 8x. What is the height of the ball after 3 seconds?
