Part A (Figure 1)A cannonball is fired horizontally from the top of a cliff. The cannon is at height H = 90.0 m above ground Assume that the cannon is fired at time t = 0 and that the cannonball hits the ground at time to. What is the y level, and the ball is fired with initial horizontal speed vo. position of the cannonball at the time to / 2? gravity to be g = 9.80 m/s2 Answer numerically in units of meters
