Answer:
t = 1 second
Step-by-step explanation:
Given: h = 16 ft
This movement is vertical free fall without initial velocity V₀ = 0
We will accept value of g= 10 m/s², but we must convert meters in the ft.
We know that 1 meter = 3.28 ft => 10 meters = 32.8 ft
According to this g= 32.8 ft/s²
The formula for calculating height is:
h = g · t²/ 2 => t² = 2 h/ g => t = √2 h / g
t = √ 2 · 16 / 32.8 = √ 32/32.8 = √ 0.98 = 0.99 ≈ 1 second
t = 1 second
God with you!!!
