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.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
