MAY 2016 PUZZLE - "The Envelope, Please?"
Submitted by Dave Thomas
You have a cannon, which can be controlled by its tilt angle and by the muzzle velocity v0. Assume that the muzzle velocity v0 is kept constant, and that the tilt angle can be varied, from shooting straight up, to shooting horizontally, as shown in the figure above.
The May Bonus:The thicker line in the figure above shows the envelope of all the positions the cannon can reach at constant muzzle velocity. What is the equation of this envelope?
