**Henry**, Sunday, September 11, 2011 at 12:01pma. Vf^2 = Vo^2 + 2gd,

d = 50 + (Vf^2 - Vo^2) / 2g,

d = 50 + (0 - (12)^2) / -19.6,

d = 50 + 7.35 = 57.35m above ground.

Vf = V0 + gt,

t = (Vf - Vo) / g,

t(up) = (0 - 12) / -9.8 = 1.22s.

b. d = (Vf^2 - Vo^2) / 2g,

d = (0 - (12)^2) / -19.6 = 7.35m above

ground.

t(up) = (Vf - Vo) / g,

t(up) = (0 - 12) / -9.8 = 1.22s.
