Expert Solution

Step 1

acceleration is change in velocity per unit time.

To find acceleration from velocity(y axis) - time(x axis) graph at a point, we have to draw tangent at that point and then find coordinates of that tangent,

so that slope=change in y coordinates/change in x coordinates

this slope is equal to acceleration at that point.
