Find initial speed and maximum height of a ball that is thrown 90 degrees straight up and lands on the ground in 3 seconds. What happens when the ball is thrown at some angle other than 90 degrees? Does it change the time of flight? Can you still determine the max height and initial speed?

2. Relevant equations

v=vo+at

Vy=Vsin90

y=vot+1/2gt^2

3. The attempt at a solution

For initial speed i did 9.81*3=29.43 to find velocity then (29.43)sin90=29.43 which i believe is the initial speed(Vo)

I'm having trouble with max height.

(29.43)(3)+4.9(3^2)=132.39m

Which i believe is much to big of a number..help please

Also I think as you move closer to 0 degrees and further away from 90 degrees, time of flight decreases, but can we determine max height and initial speed?
