Homework Question 10

If an ball is kicked off a field with unknown intial velocity and angle, determine the time needed for flight given Maximum height reached was 7 m and Range is 10 m? Determine the angle needed as well as the intial velocity!

Is it wrong to assume time is merely, t= Maximum height/gravity? Why?

If angle is unknown and velocity is unknown. Why would assuming that Maximum height achieved is only related to gravity wrong? Since it does not accelerate in the X direction at all. The range has nothing to do with Time variable.
