A car moves in a straight line at 22.0 m/s for 9.0 miles, then at 30.0 m/s for another 9.0 miles. (a) Is the car's average speed less than, greater than, or equal to 26.0 m/s? O less than 26.0 m/s equal to 26.0 m/s greater than 26.0 m/s (b) Calculate the car's average speed in meters/second. (Enter your answer to three significant figures.) m/s
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.
