n engineer is setting a speed limit on a road. She wants a car to be able to stop in 50ft and knows that the maximum rate at which a car can safely brake is 25.0ft/s?. 'hat initial speed (in given units) will allow the car to come a stop at the stop sign hen braking with this acceleration? mph puld a car traveling 65mph come to a stop before the stop sign?
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.
