Question

The velocity as a function of time of a moving object is presented by the graph to the right. Use the graph below for the following questions.What is the magnitude of acceleration of the object between 6 s and 10 s in m/s per second?

Answer 1

ANSWER:

1 m/s per second

STEP-BY-STEP EXPLANATION:

We can calculate the acceleration by the following formula and with the help of the graph.

Just like this:

$\begin{gathered} a=\frac{\Delta v}{\Delta t}=\frac{v_f-v_i}{t_f-t_i} \\ \\ \text{ We replacing} \\ \\ a=\frac{0-4}{10-6}=\frac{-4}{4}=-1\text{ m/s}^2 \end{gathered}$

The acceleration is negative, this tells us that from the second 6 the object began to slow down, but its magnitude is 1 m/s²
