How long will it take the object to hit the ground? Round the answer to the nearest thousandthThe height h in feet of an object after t seconds is given by the function?
H = 0 for the ground.
=%26gt; 0 = - 16t^2 + 30t + 7
=%26gt; 16t^2 - 30t - 7 = 0
=%26gt; t = (1/32) * [ 30 + 鈭?900 + 4*7*16)]
= 2.085 s.The height h in feet of an object after t seconds is given by the function?
to hit the ground therefore h=0
T=2.084847484. s
