A cheetah can accelerate to 60mph (26.8 m/s) in 2.90 seconds! How long will it take a cheetah to run 40 meters starting from rest? Please show work.

It will take 2.94 s to run 40 meters starting from rest.

Explanation:

Given that,

Initial speed of cheetah, u = 0

Final speed of cheetah, v = 26.8 m/s

Time, t = 2.9 s

We need to find how long will it take a cheetah to run 40 meters.

First finding acceleration of cheetah ,

Let it will take t seconds. So, using second equation of motion to find it.

So, it will take 2.94 s to run 40 meters starting from rest.
