Again, it's a bit difficult to understand what you've written. Please type out your equations here, not handwritten on paper.@Doc Al Now what?
(A) Start here: In terms of the horizontal distance traveled (I'd call it "d") and the angle of the ball's initial velocity (θ) express the initial height of the can.
(B) Solve for the travel time for the shot to cover that horizontal distance. (In terms of those variables.)
(C) Write an expression for the height of the ball at that time. (Measured from ground level.)
(D) Write an expression for the height of the can at that time. (Measured from ground level -- that's where the initial height of the can is needed.)
