What is the average acceleration? a) 5 m/s² in the direction of motion of the object b) 5 m/s² in the direction perpendicular to the motion of the object c) 5 m/s² in the direction opposite to the motion of the object d) √5 m/s² in the direction of the motion of the object 10. The motion of a projectile is described in a coordinate system. At a particular instant, the magnitude of the horizontal component of velocity is 5 m/s and the magnitude of the vertical component of the velocity is 8 m/s. What is correct about the object? a) The projectile is at its maximum height. b) The projectile is about to hit the ground c) The projectile is ascending d) The projectile has hit the ground

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.
