1. A particle started at x0 = 2 m moved at a velocity 3t^2 m/s. Find the final position of the particle at t =3 s. CHOICES x = 27 m x = 29 m x = 31 m x = 33 m 2. Two particles are moving at two different speeds, v1 = 4t^2 m/s and v2 = 2t^3 m/s. At what time will the two objects have the same value for acceleration? CHOICES 0.9683 s 1.1356 s 1.3333 s 2.3333 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.
