Homework Help: physics

Posted by physics on Thursday, December 25, 2008 at 3:13pm.

i have to build a catapult that will fire a projectile that will pass a 1m tall wall 1 m away from starting point and land in a target 1 m away from the wall. the catapult cant be more than 23cm high.

I'm having some problems here with this

for simpicity issues
i said launch at .2m off the ground at origin and reach a height of 1.1m at 1m away just incase something screws up.

I need to find the
Vi
Vyi
Vxi

and am having some trouble and dont know what angle is best so that less speed is needed for this to work
