If an object is dropped from the height of 54 feet the function h=-16t2 +54 gives the height of the object after t seconds approximately how long will it take before the object hits the ground

t= +/-

Step-by-step explanation:

set h=0, 0=-16+54, add the -16 to the other side, 16=54, divide the 16 off, =, square root both sides, t= +/- , t= +/- /4, t= +/- , the object will hit the ground when t= +/-
