From approximately what floor of a building must a baseball be dropped with an initial velocity of 10 ft/s downwards, so that it reaches a speed of 600 feet per second when it hits the ground? Each floor is 10 feet higher than the one below it. (Hint: use the velocity acceleration equation, noting acceleration of gravity is g = -32.2 ft/s^2)
V = 10 ft/s
h = feet
N = ? floors
V = 600 ft/s
