An arrow was shot directly up in the air with a velocity of 30.0 [m/s]. Air resistance is disregarded. A.) what is the maximum height reached by the arow? B.) How long will it stay in the air? Afterwards some time, a second arro w was shot directly up in the air so that both arrows collide once the second arrow reaches a maximum height of 24.0 [m]. C.) what must be the initial velocity of the second arrow? D.) how long after shooting the first arrow should the second one be launched?
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.
