A ball is thrown upward from the edge of a flat roof 80 m above the ground. The ball rises and then falls with insignificant air resistance, and strikes the ground. The initial velocity of the ball is 90.0 m/s Consider all quantities as positive in the upward direction. The velocity of the ball when it is 56 m above the ground is O 81 m/s. O -64 m/s. O 93 m/s. O -48 m/s. O -93 m/s.
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.
