Sarah is driving on a freeway in a forest at 13.0m/s when suddenly a deer runs in front of her and stands still out of fright. The deer is 20.0m in front of Sarah when she steps on the brakes with a deceleration of magnitude 4.59 m/s2 A) Find the stopping distance of Sarah. Does she hit the deer? Give support to your explanation. B) How long (how much time) does it take Sarah to travel half of the stopping distance in part (a)?
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.
