On a hot day in the flats, the temperature is 106.2 degrees. A driver finds an empty, flat stretch of desert that is 1913 meters long and decides to push the limits of his car. He finds the car can accelerate from O to 60 mph (26.8 m/s) in 4.95 s. Now he wants to see how fast the car can go. Assume the car maintains the same average acceleration until it reaches its tok speed of 87.9 m/s. (a) How long will it take the car to reach its top speed? (b) How far will the car travel before it reaches its top speed?
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.
