44. •Cody starts at a point 6 km to the east and 4 km to the south of a location that represents the origin of a coordinate system for a map. He ends up at a point 10 km to the west and 6 km to the north of the map origin. (a) Find his average velocity if the trip took him 4 h to complete. (b) Cody walks to his destination at a constant rate. His friend Marcus covers the distance with a combination of jogging, walking, running, and resting so that the total trip time is also 4 h. How do their aver- age velocities compare?
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
Given:
The time taken for the trip = 4 hour
Initial coordinates = 6 km to the east and 4 km to south
Ending point coordinates = 6 km to the north and 10 km to the west
