The object will fall through a distance of 638.45 m.
Considering the question given above, the following data were obtained:
Time (t) = 11.3 s
<h3>Height (h) =? </h3>
<u>NOTE</u>: Acceleration due to gravity (g) = 10 m/s²
We can obtain the height as illustrated below:
H = ½gt²
H = ½ × 10 × 11.3²
H = 5 × 127.69
<h3>H = 638.45 m</h3>
Therefore, the distance the object will fall is 638.45 m

It would decrease because the frequency is decreasing
The height of the flare relative to ground is 202.3 m. <em>This is the sum of height reached by the flare and the 3 m platform above the ground.</em>
<h3>
Maximum height reached by the flare</h3>
The maximum height reached by the flare is determined from the principle of conservation of energy as shown below;
P.E = K.E
mgh = ¹/₂mv²
gh = ¹/₂v²
h = (v²)/(2g)
where;
- v is the speed = 225 km/h = 62.5 m/s
h = (62.5)²/(2 x 9.8)
h = 199.3 m
<h3>Height of the flare relative to ground</h3>
H = 199.3 + 3
H = 202.3 m
Thus, the height of the flare relative to ground is 202.3 m. This is the sum of height reached by the flare and the 3 m platform above the ground.
