Question

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.

Answer 1

0.0269 seconds

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:

`\begin{gathered} v=(\Delta d)/(t) \\ \text{ solving for t} \\ t=(\Delta d)/(v) \\ t=(0.320-0)/(11.9) \\ t=0.0269 \end{gathered}`

Time is 0.0269 seconds
