A certain cannon has a maximum horizontal range of 1010m when fired on level ground. In class (and in the textbook), we derived an equation that gives the horizontal range in terms of the muzzle velocity (really, speed) vo, and the firing angle, and discussed conditions for maximum horizontal range on flat ground. (a) Use this equation to find the muzzle velocity of the cannon (b) If instead of flat ground, the cannon is fired from a hill-top at 30

Question
A certain cannon has a maximum horizontal range of 1010m when fired on level ground. In class (and in the textbook), we derived an equation that gives the horizontal range in terms of the muzzle velocity (really, speed) vo, and the firing angle, and discussed conditions for maximum horizontal range on flat ground. (a) Use this equation to find the muzzle velocity of the cannon (b) If instead of flat ground, the cannon is fired from a hill-top at 30 degrees and the projectile lands 1300m away, what is the height of the hill?
