Question

10 using a formula from physics, a sky diver knows that she can free fall for √875 s before opening her parachute. a) about how many seconds (to the nearest 0.01 s) can she free fall? b) for her next jump, she can free fall for 29.55 s. does she have more time on her first or second jump? explain using a number line.

Explanation:

Step1: Calculate square - root value

$\sqrt{875}\approx29.58$ (using a calculator)

Step2: Compare values on number line

On a number line, the larger number is to the right of the smaller number. Since $29.58>29.55$, the first - jump free - fall time is longer.

Answer:

a) $29.58$ s
b) She has more time on her first jump. On a number line, $29.58$ is to the right of $29.55$, indicating that $29.58>29.55$.
