Putting determination the receiver location aside, I would assume the goal would be to solve for azimuth angle, elevation angle and initial velocity to minimize the kinetic energy of the can when it reaches the receiver. I guess when you think about it, if one expects the receiver (hand) to exist on a given horizontal plane, then with the calculation of azimuth the problem has been reduced to the simple 2D problem presented in high school physics texts. Of course you might have to take in to account maximum height of projectile being limited to ceiling height, so you might need variable velocity on the projectile complicating the machine just a bit. Maybe one is better served by walking over to the fridge. Ron **************An Excellent Credit Score is 750. See Yours in Just 2 Easy Steps!
