- What is the acceleration of the object between times and ?
- What is the acceleration of the object between times and ?
- What is the net displacement of the object between times and ?

- The - graph is a straight-line between and , indicating
constant acceleration during this time period. Hence,

- The - graph is a straight-line between and , indicating
constant acceleration during this time period. Hence,

The negative sign indicates that the object is decelerating. - Now, , so

In other words, the net displacement between times and equals the area under the - curve, evaluated between these two times. Recalling that the area of a triangle is half its width times its height, the number of grid-squares under the - curve is 25. The area of each grid-square is . Hence,
