Answer:
14 m/s
18 m/s
22 m/s
Step-by-step explanation:
The car is moving at constant acceleration, so we can find its velocity at time t using the equation:
![v=u+at](https://img.qammunity.org/2020/formulas/physics/middle-school/8u69t2dm31jy4f6e8h3i9msisjzkrvuvq4.png)
where
u = 10 m/s is the initial velocity
is the acceleration
t is the time
Substituting the different times, we find:
At t = 2 s:
![v=10+(2)(2)=14 m/s](https://img.qammunity.org/2020/formulas/physics/middle-school/uct9taeb4y8m7t0v58l3k6d6ee9gr12u07.png)
At t = 4 s:
![v=10+2(4)=18 m/s](https://img.qammunity.org/2020/formulas/physics/middle-school/fin00g0wnp5r61afmjxbfifs3g7omswyje.png)
At t = 6 s:
![v=10+2(6)=22 m/s](https://img.qammunity.org/2020/formulas/physics/middle-school/via6gpks5oictha6za39xf9bk2f3ueg4lg.png)
