A motorist is about to enter the exit ramp of a highway. When it is 50 m before reaching A (along the straight path), the motorist travels at 80 km/h, decreasing at the rate of 0. 5 m/s 2 until it reaches B. After it reaches B, it travels at a constant speed. Determine the magnitude of the acceleration: a. just after A b just beforeR
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.
