km km A driver traveling at 100: notices the speed limit changes to 50 The driver takes 0.9 s to slow h km down to 50 with constant acceleration. We want to know how many meters the driver travels while slowing down. Which kinematic formula would be most useful to solve for the target unknown? Assume the initial direction of travel is the positive direction. Choose 1 answer: (A) v=v0+at B Az = vot+ Az = +2aAz v+v0
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.
Given data:
