Short computation The position of an object as a function of time is given by x(t) = bt4 - ct2 + et, where b = 7.9 m/s4, c = 9.42 m/s², and e = 6.58 m/s. What is the object's instantaneous acceleration a when t = 0.3 s? m/s² Remember to include a "-" if the acceleration turns out to be negative. Do not include a "+" for a positive value. a = Report your numerical answer below, assuming three significant figures.
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.
