Question

I need to know how to figure out the final and initial velocity to calculate the change in velocity by subtracting final velocity by the initial velocity. I’m not quite sure what my final and initial velocity is. I included pictures of info i collected that’s on a graph, because i’m sure that will be needed.

Answer 1

Here, in the table suppose you want to calculate the change in velocity from 5 sec to 6 sec then the velocity at 6 sec will be taken as final velocity and the velocity at 5 sec will be taken as initial velocity.The change in velocity from 5 sec to 10 sec can be calculated as,

`\begin{gathered} \Delta v=90.0\text{ cm/s-45.0 cm/s} \\ =45.0\text{ cm/s} \end{gathered}`
