A race car's velocity increases from 3.1 m/s to 49.4 m/s over a 10-s time interval. What is its average acceleration?

Question

I need to check my  answer

Answer 1

Hi Karina;

[(49.4 m/s)-(3.1 m/s)]/10 s=average acceleration

Our first priority is to verify that units match.

The left side is m/s every second.  That is the definition of acceleration.

(46.3 m/s)/10 s=average acceleration

4.63 m/s²=average acceleration

 

Is this the answer you had?

If the units match, you should have the correct answer.
