(3) If a projectile is launched into the air at 29.4 feet per second from aheight of 60 feet, its height (in feet) is given by S(x) = 60 + 29.4x - 9.8x², where x is in seconds. Showing all working, determine: (a) How long will it take the projectile reach its maximum height? (b) What is the highest height that the projectile can attain?
