**Damon**, Sunday, September 30, 2012 at 10:18amsolve two problems seperately

Problem 1 - vertical

Vi = 200 sin 53

v = Vi - 9.8 t

top when

0 = Vi -9.8 t solve for t

That t is half the time it is in the air

h = Vi t - 4.9 t^2 at time t

total time in air = 2 t

Problem 2, horizontal

u = Vi cos 53 until it crashes

d = u * total time = 2 u t
