A ball is thrown into the air by a baby alien on a planet in the system of Alpha Centauri with a velocity of 34 ft/s. Its height in feet after t seconds is given by y = 34t – 14t?. A. Find the average velocity for the time period beginning when t = 1 and lasting .01 s: 19.86 .005 s: 19.92 .002 s: 19.922 .001 s: 19.986 NOTE: For the above answers, you may have to enter 6 or 7 significant digits if you are using a calculator. B. Estimate the instantaneous velocity when t = 1.
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.
