The Tesla Model S P85 electric car accelerates from 0 to 30 mph in 1.4 s, 0 to 60 mph in 3.5 s and 0 to 110 mph in 12.1 s. Estimate how far from the start (in meters) the car is at t=12.1 s. You are given limited information about the motion of the car, so you will need to make some reasonable assumption about how it accelerates. Describe what assumption you used to solve the problem.
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.
