To find the time, plug into a kinematics chart:
Solve for t using the second star equation for kinematics (**): Δx = vo t + ½at 2 , where vo is zero;

How to Do It
For a position–time graph, the slope is the velocity. For a velocity–time graph, the slope is the
acceleration, and the area under the graph is the displacement.
The Drill
Use the graph to determine something about the object’s speed. Then play “Physics Taboo ”: suggest what
object might reasonably perform this motion and explain in words how the object moves. Use everyday
language. In your explanation, you may not use any words from the list below:
velocity
acceleration
positive
negative
increase
decrease
it
object
constant
