You throw a ball into the air from a height of 6 feet with an initial vertical velocity of 48 feet per second. Use the vertical motion model, h ( t ) = − 16 t 2 + v t + s where v is the initial velocity in feet/second and s is the height in feet, to calculate the maximum height of the ball. Round your answer to the nearest tenth if necessary. A. 30 feet B. 42 feet C. 6 feet D. 150 feet
