**bobpursley**, Sunday, May 13, 2012 at 7:16pmHorizontal:

97.5=vi*5.5

so vihorizontal= 97.5/5.5 m/s

vertical: at the top, the vertical veloicty is zero, so

0=viy-1/2 g*3^3

viy=4.9*9g

so now we have the vertical and horizontla components.

finally

hf=viy^t-1/2 g t^2 so at t=5.5, knowing viy, calculate hf.
