C. 3. While cruising along a dark stretch of highway with the cruise control set at 25 m/s (~55 mph), you see, at the fringes of your headlights, that a bridge has been washed out. Due to reaction time it takes you 3.0 seconds to begin applying your breaks. After you apply the brakes it takes an additional 4.0 s to come to a stop. Assume the clock starts the instant you notice the washed out bridge. b. d. a. Construct quantatatively accurate graphical representations of the situation described above to illustrate: x vs. t V vs. t C. a vs. t Be sure to label the axes of the graphs. [3] a. b. -+-+ +-- I + I +-+ On the v vs t graph above, graphically represent the car's distance from the origin during the 7 seconds it takes to stop. Utilizing the graphical representation (from v vs. t), determine how far the car traveled during mod braking. (Please explain your problem solving method.) [2] Using your equations of linear motion, solve for the determine how far the car traveled during mo braking. [3]
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.
