Question

Calculate the average acceleration when a vehicle is moving with a velocity from 3 m / s to 5 m / s in a time interval from 4 s to 6 s .

Answer 1

ANSWER

$1m/s^2$

EXPLANATION

The average acceleration of a body is the change in velocity divided by the change in time. That is:

$a=\frac{v_2-v_1}{t_2-t_1}$

Therefore, the average acceleration of the vehicle is:

$\begin{gathered} a=\frac{5-3}{6-4}=\frac{2}{2} \\ a=1m/s^2 \end{gathered}$
