A ball is thrown directly upward at a speed of 64 feet per second from a cliff that is 80 feet above the ground. a) Find expressions for the velocity and height of the ball t seconds after it was released. b) At what time does the ball reach its highest point? How high above the ground at the base of the cliff does it reach? c) When does the ball strike the base of the cliff? What is its velocity at that instant?
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.
