Question

Marsha's car accelerates at an average rate of 3 m/s2. How long does it take for her car to speed up from 10 m/s to 15 m/s?

Answer 1

Step-by-step explanation:

We are going to use the following equation:

`v = v_0 + at \Rightarrow t = (v - v_0)/(a)`

`t = \frac{15\:\text{m/s} - 10\:\text{m/s}}{3\:\text{m/s}^2}`

`\:\:\:\:=1.67\:\text{s}`
