A cannonball is fired horizontally from the top of a cliff. The cannon is at height h = 50.0 m above ground level, and the ball is fired with initial horizontal speed v(initial). Assume acceleration due to gravity to be g = 9.80 .
Given that the projectile lands at a distance = 130 from the cliff, as shown in the figure, find the initial speed of the projectile,v(initial)??
