I used to be good at phyics, but.... That was 1987!!! I was at the range the other day with some guys when the question of maximum cannon range came up. I knew it had to be 45 degrees but that was all I could remember. 1. The problem statement, all variables and given/known data A cannon fires a 1kg iron ball at a 45 degree angle with an initial muzzle velocity of 500 m/sec and a muzzle height of 5 ft. Assume level terrain, no wind resistance, and no other complicating factors. Find the time in flight, maximum height, and total horizontal distance travelled. 2. Relevant equations All I remember is that 9.8m/s^2 is part of this 3. The attempt at a solution Hide in corner in fetal position remembering physics class again! Seriosuly, go to the pros when you want the right answer. Can you please tell me what is the formula for these answers? Thanks!
