A driver finds that her car will descend the slope e, = 3.7° at a certain constant speed with no brakes or throttle required. The slope decreases fairly abruptly to 02 at point A. If the driver takes no action but continues to coast, determine the acceleration a (positive if the car speeds up, negative if it slows down) of the car just after it passes point A for the conditions (a) 02 = 2.2° and (b) 02 = 0°. v= constant Answers: (a) a = i m/s2 (b) а - m/s2
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.
