A projectile is launched from ground level with an initial velocity of Vo feet per second. Neglecting air resistance, its height in feet t seconds after launch is given byS = - 16t^2 + Vot. Find the time(s) that the projectile will (a) reach a height of 128 ft and (b) return to the ground when Vo = 96 feet per second.(a) Find the time(s) that the projectile will reach a height of 128 ft when Vo = 96 feet per second. Select the correct choice below and, if necessary, fill in the answer to complete your choice.(А) ____ seconds (Use a comma to separate answers as needed.)(B) The projectile does not reach 128 feet.(I included a picture of the problem for reference and clarity because i could not input the correct mathematical language .
