A vehicle is accelerating at 12m/s2 along a flat road (with coefficientof friction = 0.3) for 5 seconds and suddenly hit the brakes 3 seconds after seeingan obstruction along its path. a. What is the braking distance? b. What is the stopping sight distance? c. Will it hit a pedestrian 600m away if it hit the brakes 1.33seconds late? (Note: Use the same vehicle speed with a and b)
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.
