A ball is shot vertically into the air at a velocity of 63 m/s. After 5 seconds, another ball is shot vertically into the air. If the balls meet 120 m from the ground, determine the relative position (in m)of the first ball to the second ball 9 seconds after the first ball was shot into the air. Use 9.81 m/s2 for the acceleration due to gravity. Round off your final answer to five decimal places.
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.
