select the correct answer. a helicopter hovers 200.0 meters over the ground and releases a relief packet. how much time does it take for the food packet to reach the ground? a. 3.7 seconds b. 4.4 seconds c. 6.0 seconds d. 6.4 seconds

Answer

Explanation:

Step1: Use free fall equation

$s = \frac{1}{2}gt^2$ (u=0, initial velocity)

Step2: Solve for t

$t = \sqrt{\frac{2s}{g}}$

Step3: Substitute values

$s=200.0m, g=9.8m/s^2$ → $t=\sqrt{\frac{2×200}{9.8}}≈\sqrt{40.816}≈6.4s$

Answer:

D. 6.4 seconds
