It is late at night and your are on the road in your SUV on Interstate 80. You are moving at a speed of 18m/s. Suddenly you see a large animal in the road 38.2 m ahead. a. Given that you can reduce your speed at a maximum rate of 4.60 m/s2, what reaction time is needed to avoid plowing into the animal? 0.20 XS b. Suppose your reaction time is about 0.3s, how fast will you be traveling when you plow into the poor moose? 3.45 X m/s
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.
