Question

A vehicle moving with a uniform acceleration of 2m/s has a velocity of 4m/s at a certain time. what will its velocity be?

Answer 1

We can find the velocity of the vehicle from the kinematic equation:

$$v = v_{0} + at,$$

here, $v_0$ is the initial velocity of the vehicle, $a$ is the acceleration of the vehicle and $t$ is the time.

Then, from this equation we can find the velocity of the vehicle 1 second later:

$$v= 4 \dfrac{m}{s} + 2 \dfrac{m}{s^2} \cdot 1 s = 6 \dfrac{m}{s}.$$

Answer:

$v= 6 \dfrac{m}{s}.$
