A delivery truck travels northward from a warehouse at 23.0 m/s and arrives at Walmart 4200. m away. The truck stays there for 67.0 s before it is ordered to turn back southward. The truck travels southward at 20.0 m/s for 48.0 s and arrives at Kroger. Choose the location of the warehouse to be the origin and northward as positive direction. Answer the following questions. Use appropriate units: m for meter, s for second, and m/s for meter per...

Consider two displacement vectors for an object along the horizontal direction, x_0 - 2 sec = 3 meters to the right and then x_2 - 5 sec = 5 meters to the left. Given that the object starts from the origin and each displacement was done with two constant speeds, answer the following questions for the 5 second trip. Plot the position of the object as a function of time. Plot the velocity of the object as a function of...
