A cannonball is fired horizontally from the top of a cliff. The cannon is at height H = 60 meter above ground level, and the ball is fired with initial horizontal speed v0. Assume acceleration due to gravity to be g = 9.80m/s2.
Part A Suppose that the cannon is fired at time t=0 and that the cannonball hits the ground at time tg. Determine what is the y position of the cannonball at the time tg/2? Answer numerically in units of meters.
