1. The problem statement, all variables and given/known data A shotputter projects the shot at 42 degrees to the horizontal from a height of 2.1 m. It lands 17 m away horizontally. Next, he gives it the same initial speed but changes the angle to 40 degrees. What effect does this have on the horizontal range? 2. Relevant equations 3. The attempt at a solution I tried solving this by algebraic means but failed to come to the answer of 0.02m less which is given in the back of the book. Not having initial velocity or time makes this problem difficult to solve but i know that by understanding how to solve this problem I can understand how to do similar problems. I would greatly appreciate any assistance. I like to do things my self so I am not asking you to do the work for me, but perhaps send me in the right direction.
