# The cheetah can reach a top speed of 114 km/h (71 mi/h)

• carrollk9
In summary, the conversation is about determining the average acceleration and displacement of a cheetah during a short sprint, assuming constant acceleration. The person asking for help has been using a velocity calculator but is still unsure of the correct answer. They are asked if they have used consistent units and reminded to show their attempted equations and steps in order for others to provide assistance.

## Homework Statement

The cheetah can reach a top speed of 114 km/h (71 mi/h). While chasing its prey in a short sprint, a cheetah starts from rest and runs 50 m in a straight line, reaching a final speed of 85 km/h.

(a) Determine the cheetah's average acceleration during the short sprint.

(b) Find its displacement at
t = 3.0 s.
(Assume the cheetah maintains a constant acceleration throughout the sprint.)

## The Attempt at a Solution

I've been using a velocity calculator but still getting the wrong answer and honestly i just don't know what I'm doing

Have you used consistent units?

You haven't provided any insight as to what equations you are attempting to use, and haven't shown an actual attempt. We can't help if we can't see what you've attempted.

## What is the top speed of a cheetah?

The top speed of a cheetah is 114 km/h (71 mi/h). This makes them the fastest land animal on Earth.

## How does a cheetah reach such high speeds?

Cheetahs have evolved to have a slender and muscular body, along with long legs and a flexible spine, which allows them to cover large distances with each stride. They also have non-retractable claws that provide traction and help them maintain balance while running.

## Can a cheetah maintain its top speed for a long period of time?

No, a cheetah can only maintain its top speed for a short burst of time, typically less than a minute. After that, they need to rest and recover before they can sprint again.

## Are there any other animals that can run as fast as a cheetah?

No, the cheetah is the fastest land animal. However, some other animals, such as pronghorns and greyhounds, can also reach high speeds, but not as fast as a cheetah.

## How do scientists measure the speed of a cheetah?

Scientists use various methods to measure the speed of a cheetah, including radar guns, camera traps, and GPS trackers. These tools allow them to accurately measure the speed of a cheetah in its natural habitat.
