Question

A soccer ball is kicked from the top of a 256 foot building with an initial velocity of 6 ft/s. What will the ball's velocity be at the instant before it strikes the ground?

Answer 1

vf2=v02+2ax

then solve for vf

the vf would then be used as v0 for the 2nd half of the projectile.

then you use the same equation to solve for vf.
