A small sphere is launched horizontally with a speed v0 toward a target a horizontal distance D away. The sphere lands on the target that is at height H below the height from which the sphere was launched. If the sphere were launched again, but with a speed 2v0 , how high above the target would the sphere have to be launched horizontally to hit the same target, still a horizontal distance D away
