An object moves along the x axis according to the equation x = 3.55t – 2.00t + 3.00, where x is in meters and t is in seconds. (a) Determine the average speed betweent = 1.80 s and t = 2.90 s. m/s (b) Determine the instantaneous speed at t = 1.80 s. m/s Determine the instantaneous speed at t = 2.90 s. m/s (c) Determine the average acceleration between t = 1.80 s and t = 2.90 s. m/s? (d) Determine the instantaneous acceleration at t = 1.80 s. m/s? Determine the instantaneous acceleration at t = 2.90 s. m/s? (e) At what time is the object at rest?
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.
