How long does it take to fall 40 feet?

Answer 1

Assuming you are on earth and you have at least 40 ft to fall:

You can use an equation of motion:

s = ut + ½at²

t = time (unknown)

u = inital velocity (0 in this case)

s = distance (40 ft)

a = acceleration due to gravity (approx 32.18 ft/s²)

s = ut + ½at²

→ 40 ft ≈ 0 + ½ × 32.18 ft/s²× t²

→ t² ≈ 40 × 2 ÷ 32.18 s²

→ t ≈ √(2.486 s²)

≈ 1.6 seconds

Answer 2

Approx 1.6 seconds.
