"A friend leans out of an upper window of an apartment building and drops a canned beverage of your choice to you on the sidewalk below. Unfortunately, you aren't directly beneath the window; instead, you are standing where the angle to your friend is 75 degrees above horizontal. Thinking quickly, you start accelerating toward the point where the falling can will reach ground level. Find the constant acceleration of your motion that would allow you to catch the can as you arrive."
The Attempt at a Solution
What I know is that I made up a weight for the can (.75 lbs), which I converted to Newtons (.75lb x 1N/.2248lbs = 3.3N). I know that I weigh 140 lbs, which I converted to 623 Newtons. The falling can has the equation F=ma, so I calculated the mass to be .34kg. The final y-position is zero--the point where I catch the can. The initial velocity in the y-direction for the can, as well as the initial velocity in the x-direction for me, are both zero. Since there is no time or final velocity given, I am really confused as to how to approach this problem. Any help/hints are greatly appreciated.
