Homework Statement
I've made a picture of the situation:
http://img11.imageshack.us/img11/7177/drawing1m.jpg
I need to find the expression for the start velocity v0. The ball should exactly hit the corner.
The function should have the distance L (Which both is x-distance and y-distance to the point) and the angle a as variables.
We can ignore air resistance.
Homework Equations
Normal projectile motion equations:
x=(v0*cos(a)*t
y=(v0*sin(a)*t-1/2*g*t^2)
vx=v0*cos(a)
vy=v0*sin(a)-gt
The Attempt at a Solution
I've been sitting with he assignment for 2 hours - trying both creative and stupid solutions!
First attempt was setting x=L and y=L and find the expression for v0.
I've also trying to set the v=0, but afterwards finding out the ball speed doesn't have to be zero.
Nothing has worked out so far.
Any suggestions?
Thanks alot.
