You are driving at night on a straight path at 70MPH. Suddenly, a dog appears in your headlights 35 meters away. You immediatley apply the brakes which causes your car to slow down at a constant rate, coming to rest just before making contact with the dog. 1 mile = 1.61 km 1) How long did it take for your car to make a complete stop? 2) If you were initially driving in the 'positive x' direction, then what was your acceleration during the braking maneuver, in vector form and in m/s2?
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.
