You’ll now apply the horizontal launch to a car accident example. In this scenario, a car driver named Joshua Horton says he was driving at the speed limit of 45 mph when he hit an icy patch and drove through a guard rail of the 15 m tall bridge, before landing 24 m from the base of the bridge. Tes1ng shows that driving through the guard rail lowers a car’s speed by 10 m/s. QUESTION 3: Given the distance that the car landed from the bridge, determine what speed Joshua was actually driving before leaving the bridge. Was he telling the truth or lying? Show your calcula1ons here.
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.
