Answer:

b

Step-by-step explanation:

When the object hits the ground , the h = 0 , that is

- 16t² + 54 = 0 ( subtract 54 from both sides )

- 16t² = - 54 ( divide both sides by - 16 )

t² = \frac{54}{16} ( take square root of both sides )

t = \sqrt{\frac{54}{16} } ≈ 1.84 seconds ( to 2 dec. places )
