The variables include acceleration (a), time (t), displacement (d), final velocity (vf), and initial velocity (vi). If values of three variables are known, then the others can be calculated using the equations. This page demonstrates the process with 20 sample problems and accompanying solutions.

solution. The problem presents us with a velocity-time graph. Do not read it as if it was showing you position. You can't immediately determine where the object is from this graph. You can say what direction it's moving, how fast it's going, and whether or not it's accelerating, however.
1. The velocity-time graph below shows the journey of a car. (a) Use the graph to estimate the speed of the car after 30 seconds. n . 2. The velocity-time graph below shows the run of a sprinter. (a) Use the graph to find the sprinter’s acceleration between 0 and 20 seconds. (b) Use the graph to estimate the sprinter’s speed after 8 seconds.
