Exciting Data About a Paratrooper's Descent

What is the formula for the paratrooper's height above the ground after t seconds?

a. h = startfraction 4500 over 20 endfraction minus t

b. h = negative 20 t 4500

c. h = 4500 20 t

d. h = startfraction 4500 over 20 endfraction t

Answer:

The formula for the paratrooper's height is h = 4500 - 20t.

Let's dive into the exciting world of a paratrooper's descent! The formula for the paratrooper's height, h, above the ground after t seconds is h = 4500 - 20t. This formula takes into account the initial altitude of 4500 ft and the descent rate of 20 ft/sec.

As the paratrooper descends at a rate of 20 ft/sec, the height decreases by 20 feet every second. Starting from the initial altitude of 4500 ft, the formula calculates the height above the ground by subtracting 20 times the number of seconds, t.

For example, if t is 3 seconds, the paratrooper would be 4500 - 20(3) = 4500 - 60 = 4440 feet above the ground.
