cody is driving down the road, eastbound, with his dog in the back seat of the car. To an outside observer on the roadside, Cody’s speed is 21.0 meters per second. A blue car is passing them at a relative velocity of 2.5 meters per second. Which of the following statements are accurate about this situation? (Choose all that apply) The blue car’s velocity, to a roadside observer, is 23.5 m/s. The blue car’s velocity, to a roadside observer, is 18.5 m
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.

The blue car’s velocity, to a roadside observer, is 23.5 m/s.
|
|
|
The blue car’s velocity, to a roadside observer, is 18.5 m/s.
|
|
|
The dog’s velocity, relative to Cody, is 0 m/s.
|
|
|
Cody’s velocity, from the blue car’s frame of reference, is −2.5 m/s.
|
|
|
Cody is stationary from the blue car’s frame of reference.
