**Damon**, Friday, February 21, 2014 at 7:24pmu = horizontal velocity = 5.7 cos 58

= 3.02 m/s forever

Vi = initial speed up = 5.7 sin 58

= 4.83 m/s

v = Vi - 9.8 t

at top, v = o

0 = 4.83 - 9.8 t

t = .493 s at top

h = 1.3 + Vi t - 4.9 t^2

t at top is .493

so

h at top = 1.3 + 4.83(.493)-4.9(.493)^2

= 2.49 meters above ground

x = u t

x = 3.02 * .493 = 1.49 meters
