A ball thrown straigh upward from the ground reaches a maximum height of 400ft. What was its initial velocity? Using the formulas:(adsbygoogle = window.adsbygoogle || []).push({});

V=at+Vo

X=1/2at^2+Vot+Xo

the distance travelled is 400ft, and the initial distance was 0. The force of gravity is -32ft/s/s. Also, the velocity of the ball at the top of the height is 0.

in the equation V=at+Vo, I don't know how to solve it with 2 variables (t and Vo)
