I have a homework problem I was told to "think about". The teacher says he did not have time to teach us a few things we should know about this, but we should think about it over the weekend so we can do it on monday. Well I am trying, but I feel like there is information I am missing. Not information in the problem, but a method to solve. A ball is given an initial velocity of 34m/s at an angle of 30degrees. Determine the distance the ball travels before it hits the ground. Can somebody give some steps of how I would best solve this problem? We just started two dimensional motion, with your I and J vectors.
