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

1 m/s per second

Explanation:

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

Just like this:

`\begin{gathered} a=(\Delta v)/(\Delta t)=(v_f-v_i)/(t_f-t_i) \\ \\ \text{ We replacing} \\ \\ a=(0-4)/(10-6)=(-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
