(3) At what horizontal velocity would you need to throw a ball off the roof of an 8.5 meter building
if you wanted it to land 62.5 meters away from the base of the building? What would be the
vertical velocity of the ball immediately before hitting the ground?
(4) Referring back to question #3, at what velocity would you need to throw the ball if you wanted it
Th=1/2gt^2
to land twice as far away?
62.5m=x(1.73s)
t=1.317 s
x=94.91 m/s
36.13m/s
