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.

For point X, draw an arrow to show the acceleration of the parcel. What is the horizontal
velocity at point X, explain your answer?
In order to achieve a range that is three times larger (3d) than the first path, what is the
initial horizontal projection velocity required for the path. Explain your answer.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F53c8e9f3-70d8-4090-b2af-4da848eb9264%2Fd7d4c749-c4ba-442d-85ee-a1e0aa277c9c%2Fe94ncl_processed.png&w=3840&q=75)
