The height ( in feet) above the earth for a sky diver t second after jumping from an
airplane at 6400 ft is approximated by the formula h=-16t 2
+6400. provided that t<5. rewrite the formula with the right hand side factored
completely use revised formula to find h when t=2.

if a ball is thrown upward at 40 feet per second from a rooftop 24 feet above the ground
,then its height above the ground t second after it isthrown is given by h=-16t^2+40t+24.
rewrite this formula with the polynomial on the right hand side factored completely . use
the factored version of the formula to find t=3.
