2. From a point 160 feet above the ground, a body is thrown vertically upward. When it is 32 feet above the starting point, it is moving downward at 1611. Find: (a). the initial velocity of motion. (b). the time when it retums back to the starting point. (c). the time and velocity when the body hits the ground. (d). the highest point of its flight measured from the ground.
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.
