Can somebody me answer this question? a car went from 110 m/s to 80 m/s in 20 seconds. what was the acceleration of the car?

-1.5m/s²

Explanation:

Acceleration can be thought of as [Change in Velocity]/[Change in time]. To find these changes, you simply subtract the initial quantity from the final quantity.

So for this question you have:

which means that the acceleration = (80-110)/(20-0)[m/s²] = (-30/20)m/s² = -1.5m/s²

the components of a vector are the parts of the vectors that are to each other.
