A car traveling at 11.9 meters per second crashes into a barrier and stops in 0.320 meters.How long does it take the car to stop? Include units in your answer. More information. Hint: This is a constant acceleration problem. Answer must be in 3 significant digits.

Respuesta :

ANSWER:

0.0269 seconds

STEP-BY-STEP EXPLANATION:

Since the acceleration is constant, we can determine that the velocity does not change with respect to time, therefore we can calculate the time as follows:

[tex]\begin{gathered} v=\frac{\Delta d}{t} \\ \text{ solving for t} \\ t=\frac{\Delta d}{v} \\ t=\frac{0.320-0}{11.9} \\ t=0.0269 \end{gathered}[/tex]

Time is 0.0269 seconds
