V. tolal hmax H 24 m Agra Fort S = 150m fig B The trajectory of a cannonball fired towards Agra Fort. We assume the cannonball leaves the cannon at ground level. In addition to the layout shown in fig B, we need information about the initial velocity of the cannonball. The cannon explosion could act for 0.05 s to accelerate the cannonball mass =12kg with force of 9300N at an angle of 45 to horizontal
