Question

What is the acceleration of a car that goes from 10 mph to the speed of 50 mph in four seconds

Answer 1

The acceleration is given by the variation of the speed divided by the time.

So:

`\begin{gathered} a=(v-v0)/(t) \\ a=(50-10)/(4) \\ a=40/4 \\ a=10m/s^(2) \end{gathered}`

Answer: 10m/s²
