car is traveling along a straight road at a velocity of +27.4 m/s when its engine cuts out. For the next 2.24 seconds, the car slows down, and its average acceleration is . For the next 3.56 seconds, the car slows down further, and its average acceleration is . The velocity of the car at the end of the 5.80-second period is +14.5 m/s. The ratio of the average acceleration values is = 1.91. Find the velocity of the car at the end of the initial 2.24-second interval.
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.
