A boy throws a rock vertically upward from the roof of a high rise building. the rock then leaves the hands of the boy at an upward speed of 15.0m/s. now, the rocks is in free fall. On its downward path, it misses the roof slab of the building. determine, 1. the object's position and speed at t= 4.0s and t=1.0s 2. the velocity of the rock 5.0m above the building's roof slab 3. maximum height reached 4. object's acceleration in no. 3
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.
