Question

A cheetah can accelerate from rest to a speed of 30.0 m/s in 7.00s. wht is its acceleration?

Answer 1

30×7=210m it is easyokok

Answer 2

The given value of the speed of cheetah is,

`v=30ms^(-1)`

The time during the speed v is,

`t=7\text{ s}`

The relation between the acceleration, speed and time is,

`a=(v)/(t)`

Substituting the known values,

`\begin{gathered} a=(30)/(7) \\ a=4.3ms^(-2) \end{gathered}`

Thus, the value of the acceleration is 4.3 meter per second squared.
