2. On top of a tower (30 m from the ground), an object is launched straight up with an initial velocity vo. The object continues its flight in free fall to a maximum height of 65 meter from top of the tower. After reaching the maximum height, the object falls back to the ground. a. What is initial velocity vo of the object (at the height of 30 m) b. What is the velocity of the object just before it hits the ground? c. What is the total duration of the object's flight? d. Draw a position-time, velocity-time, and acceleration-time graph to show the motion of the object
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.
On top of a tower (30 m from the ground), an object is launched
straight up with an initial velocity ?0. The object continues its flight in free fall to a maximum height of 65 meter from top of the tower. After reaching the maximum height, the object falls back to the ground.
