Question

1. a cheetah can run at a maximum speed of 30.0 km/h, or 8.33 m/s. how far can a cheetah run in 3.27 s?
2. how long does it take a rock to fall through 2.8 m of water if it falls at a constant speed of 1.2 m/s?

Explanation:

Step1: Recall distance formula

Distance $d = v \times t$ (constant speed)

Step2: Calculate cheetah's distance

$d = 8.333 \, \text{m/s} \times 3.27 \, \text{s} \approx 27.2 \, \text{m}$

Step3: Recall time formula

Time $t = \frac{d}{v}$

Step4: Calculate rock's time

$t = \frac{2.8 \, \text{m}}{1.2 \, \text{m/s}} \approx 2.3 \, \text{s}$

Answer:

27.2 m
2.3 s
