Alice throws a ball (almost) straight up from the top of a 30-m-high tower at t=0. The initial velocity of the ball is 5 m/s. The ball rises, then falls back along the wall of the tower and lands on the ground. Make a diagram showing the vertical position of the ball vs. time. Clearly label the axes. Display the numerical values of the maximum elevation of the ball, the time when it passes by Alice on its way down and the time when it hits the ground on the diagram.
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.
