**bobpursley**, Wednesday, November 3, 2010 at 5:41pmHorizontal equation:

96.4=VicosTheta*4.7

Vertical equation:

h=ViSinTheta*4.7-4.9(4.7^2)

one last equation: at max height, vy=0

0=ViSinTheta*2.6-4.9(2.6^2)

Lets see. Solve the third equation for VisinTheta, put that into the second equation, solve for h (answer b)

then max height:

hmax=visintheta(2.6)-4.9(2.6^2)

solve for hmax using the same expression you had in equation 3.
