Stupid Cannon Problem

[caharris]

"John is 1.5m tall and throws an orange at a velocity of 15m/s. It just barely clears a 5m tall wall at the peak of its trajectory. At what angle did he throw the ball? How far away is John from the wall?"

 

So pretty much, the only thing I can't remember is how to find Vx and Vy. (To get the angle.) I know I have to break V down into components to find the angle, and I know V will be the hypotenuse of the triangle used to find the angle. Would I just use formulas to find Vf to find Vy (If I remember correctly, V is also Vx to begin with)?

 

All I need is to know whether you find Vf to get Vy, I have the formulas for that.

Thank you for your help.

First, solve for the vertical component of the velocity, and with that you can calculate the x component. You'll also need to find out how long it took the orange to go up from 1.5 m to 5 m.
