5. An object is pushed along a rough surface and released. It slides for 10.0 s before coming to rest and travels a distance of 20.0 cm during the last 1.0 s of the slide. Assuming the acceleration is uniform throughout, (a) How fast was the object traveling upon release? [Ans: 4.0m/s] v; (b) How fast was the object traveling when it reached the halfway point in its slide? [Ans: 2.8m/s] V
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.
