You throw a ball vertically upward from the roof of a building the ball leaves your hand at a point even with a roof railing with an upward speed of 15m/s .The ball is then to free to fall. Find the following: a. The position and velocity of the ball 1.0s and 4.0 s after leaving your hands ( Sts =10.095 m, Se=-18.48 m, Vi=5.19m/s, Va-24.24m/s) b. The velocity when the ball is 5.0m above the railing (v = +11.26m/s) c. The maximum height reached and the time at which it is reached (tma=1.529s, Smar=11.467) d. The acceleration of ball when it is at its maximum height
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.
