Question

bridgette, a wildlife filmmaker, is working on a documentary about cheetahs. this morning, she starts filming a cheetah while it prowls around at a slow pace. suddenly, the cheetah puts on a burst of speed to chase its prey, remaining at peak speed for just a few moments. then, it stops to eat its meal. not long after that, bridgette stops filming. which graph could show the cheetahs speed over the time bridgette was filming?

Explanation:

Step1: Analyze cheetah's speed - start

The cheetah starts at a slow - pace speed. So the graph should start at a non - zero, relatively low speed value.

Step2: Analyze cheetah's speed - chase

Then it has a burst of speed to chase prey, so the speed increases rapidly.

Step3: Analyze cheetah's speed - peak

It remains at peak speed for a few moments, so there should be a horizontal section at the higher speed value.

Step4: Analyze cheetah's speed - stop

Finally, it stops to eat, so the speed drops to zero.

Answer:

The first graph (top - left) is the correct one as it starts at a non - zero low speed, has a rapid increase to a peak speed, a horizontal section at the peak speed, and then a rapid drop to zero speed.
