A cannon shoots straight up into the air a cannonball which reaches a maximum height of 600m. What was the initial velocity of the cannonball when it was fired from the cannon. (Note: this problem contains all the information necessary to be solved.)
The Attempt at a Solution
I have no clue as to how you would solve for the initial velocity without the mass of the cannon ball. Obviously, the initial velocity depends on the mass of the ball because a cannonball with more mass will need to be travelling at a higher velocity to reach 600m. Do I need to calculate the mass some how? Can someone point me in the right direction?
