if the coef The maximum acceleration on the car without causing the cup to slide is 21 ms squared what is the smallest amount of time in which the person can ac class=

Respuesta :

We will have the following:

We will determine the minimum time it would take as follows:

[tex]\begin{gathered} (\frac{23m/s-0m/s}{t})=2.1m/s\Rightarrow t=\frac{23m/s-0m/s}{2.1m/s} \\ \\ \Rightarrow t=\frac{230}{21}s\Rightarrow t\approx10.95s \end{gathered}[/tex]

So, the minimum time will be approximately 10.95 seconds.
