1. The problem statement, all variables and given/known data A boy throws a ball upward with a speed of vo= 12m/s. The wind imparts a horizontal acceleration of 0.4m/s^2 to the left. At what angle theta must the ball be thrown so that it returns to the point of release. (assuming wind does not affect vertical motion. 2. Relevant equations All physics equation 3. The attempt at a solution I have written down all the formulas in the x and y directions, but it doesnt work out. I have also tried to look for what distance Vy=0 but i still end up having 2 unknowns.
