Velocity vs time graph1/5/2024 ![]() ![]() And then drawing a velocity versus time graph of that situation, we have that initially the velocity is at it's greatest when the hand is, just at the moment it is no longer touching the book and releases it. So from 8 until 12 this position has not changed. So eventually this book is going to move along here 'till finally at 8 seconds, it stops. Our position-time graph, well it starts at, let's say we call this position zero and then it slowly is changing its slope until the point where it's no longer moving at all once it gets to 8 seconds because at that point, its position is at 30. Give some units, centimeters and seconds and do some realistic numbers. So, let's draw our vertical and horizontal axes and label them with what they are position on one hand and horizontally it's Time. Now, we also assume that we begin drawing a graph at the moment when the person's hand is no longer touching the book and so it's just slowly slowing down as a result of sliding friction with the table. We're going to draw position-time graphs and velocity-time graphs for this book sliding across a horizontal table assuming that initially it's going in the positive direction, and then in the second case, assuming that it's initially going in the negative direction.
