Question 661997: Please help me solve this problem, i've tried but i just can't figure it out! A projectile is fired vertically upward from a height of 600 ft above ground. it's height h(t) in feet above the ground after 't' seconds is given by: h(t)= -16x^2+803x+600. Find the time 't' at which the projectile reaches maximum height, the maximum height reached by the projectile, and the time when the projectile hits the ground. Thank you for your help!!
