3. The rectilinear motion of a particle is governed by the equation a = 6t – 4 where a is in m/s^2 and t is in seconds. When t=0, the acceleration of the particle is 4 m/s^2 to the left. During the interval from t=2 to t=4s, the displacement of the particle is 20 m to the right. Determine: a. The initial velocity of the particle b. The velocity of the particle at the end of the displacement period The position of the particle when t=3s c.
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.
