Ann and Teller decided to do a magic trick involving a coin and a base- ball. Ann throws the baseball straight upwards from the ground with an initial velocity of V0.coin = 5 [m/s] j. At the exact moment that the baseball was released, Teller throws the coin with an initial velocity of vo,bal = 10 [m/s] î + 5 [m/s] j from the ground. Which of the following is true about the two objects? %3D A. The baseball will reach the ground first. B. The coin will reach a greater height. C. Both objects will reach the ground at the same time. D. The baseball will reach the ground last.
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.
