A particle moves along a straight line such that its position is defined by s=(t^2−6t+5)m. (a) Determine the average velocity of the particle when t = 7.9 s . Express your answer to three significant figures and include the appropriate units. The answer is not 9.8 m/s (b) Determine the average speed of the particle when t = 7.9 s. Express your answer to three significant figures and include the appropriate units. The answer is not 1.9 m/s (c) Determine the acceleration of the particle when t = 7.9 s. Express your answer to three significant figures and include the appropriate units.
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.
