A car initially at rest begins to accelerate at 1.25 m/s2 until its speed reaches 90.0 km/h and then continues to move at 90.0 km/h for 5.00 minutes. (i) Find the time the car takes to reach 90.0 km/h from rest (ii) Determine the displacement of the car throughout the acceleration (iii) Calculate the total displacement of the car throughout the drive
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.
