Answer to Question #164944 in Physics for Praise

Question

A vehicle moving with a uniform acceleration of 2m/s² has a velocity of 4m/s at a certain time.What will its velocity be? At 1s later and at 5s later

Answer 1

We know that

$$v(t)=v_0+at,$$

so:

$$v(1)=4+2·1=6\text{ m/s},\\ v(5)=4+2·5=14\text{ m/s}.$$
