Answer:

t = √(2d/g); 3.70 s

Step-by-step explanation:

The formula for the distance (d) travelled by a falling object in time (t) is

d = ½gt²

Multiply each side by 2 2d = gt²

Divide each side by g (2d/g) = t²

Take the square root of each side t = √(2d/g)

Data:

d = 220 ft

g = 32.17 ft·s⁻²

Calculation:

t = √ [(2 × 220)/32.17] = √13.68 = 3.70 s

The ball will hit the ground 3.70 s after it is released.
