**drwls**, Sunday, December 2, 2007 at 7:40pmThe equations are:

x = 133 cos(35)* t

y = 5 + 133 sin 35 * t - (1/2) g t^2

It will remain in the air until y = 0. (Solve then y equation for t).

g = 9.8 m/s^2.

Maximum height is attained when

Vy = 133 sin 35 - gt = 0.

Solve for t. That is the time when the height is a maximum. Then insert that t into the equation for y(t). That will give you th3e maximum height.
