A person, standing on the top of a 50 m high building, throws two stones vertically downward 1.00 second apart and observes they hit the ground at the same time. The first stone had an initial velocity of -2.00 m/s. What must be the initial velocity of the second stone so that both stones will hit the ground at the same time. A.) -23.5 m/s B.) -15.2 m/s C.) -7.1 m/s D.) -31.9 m/s
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.
