Now that we know how long the cannonball is in the air, it's a simple matter of using our equation for horizontal displacement. The only difficulty is that we must first find the horizontal component of the initial velocity:

The phrase constant velocity indicates a motion with a 0 acceleration. The acceleration of the object during the last 5 seconds can be calculated using the following kinematic equation. The displacement of the object during the entire 10 seconds can also be calculated using kinematic equations.

Since these 10 seconds include two distinctly different acceleration intervals, the calculations for each interval must be done separately.

This is shown below.

The analysis of this simple motion illustrates the value of these two representations of motion - velocity-time graph and kinematic equations. Each representation can be utilized to extract numerical information about unknown motion quantities for any given motion.

The examples below provide useful opportunity for those requiring additional practice. Check Your Understanding 1. Rennata Gas is driving through town at Eventually Rennata comes to a complete stop. Represent Rennata's accelerated motion by sketching a velocity-time graph.

Use the velocity-time graph to determine this distance. Use kinematic equations to calculate the distance that Rennata travels while decelerating.

See Graph and Answer 2. Otto Emissions is driving his car at Otto accelerates at 2. Otto then maintains a constant velocity for Represent the 15 seconds of Otto Emission's motion by sketching a velocity-time graph.

Use the graph to determine the distance that Otto traveled during the entire 15 seconds. Finally, break the motion into its two segments and use kinematic equations to calculate the total distance traveled during the entire 15 seconds.

Kinematics w/ Graphs. An object's position during a 10 second time interval is shown by the graph below: a.) Determine the object's total distance traveled and displacement. This graph uses horizontal lines instead of points to represent that the acceleration is defined at that value at any point along that.

Chapter 4 One Dimensional Kinematics In the first place, what do we mean by time and space? It turns out that these deep philosophical questions have to be analyzed very carefully in physics, and this is not easy to do. The theory of relativity shows that our ideas of space and time are On a graph of the x-component of velocity vs.
