A car is traveling along a straight road at a velocity of +28.8 m/s when its engine cuts out. For the next 1.42 seconds, the car slows down, and its average acceleration is a,. For the next 3.20 seconds, the car slows down further, and its average acceleration is a,. The velocity of the car at the end of the 4.62-second period is +14.9 m/s. The ratio of the average acceleration values is ā/ā, - 1.84. Find the velocity of the car at the end of the initial 1.42-second interval. = Number Units
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.
