. A ball is thrown vertically upward with a velocity of 20 m/s from the top of a tower having a height of 50 m. On its return, it misses the tower and finally strikes the ground, What time t1 elapses from the instant the ball was thrown until it passes the edge of the tower? What velocity v1 does it have at this time? What total time t2 is required for the ball to reach the ground? With what velocity v2 does it strike 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.
