A cannonball is fired horizontally from the top of a cliff. The cannon is at height H = 70.0 m above ground level, and the ball is fired with initial horizontal speed v0. Assume acceleration due to gravity to be g = 9.80 m/s2. Given that the projectile lands at a distance D = 150 m from the cliff, find the initial speed of the projectile, v0. Express the initial speed numerically in meters per second.
