An arrow is shot from a height of 1.5 m toward a cliff of height H. It is shot with a velocity of 31 m/s at an angle of 60° above the horizontal. It lands on the top edge of the cliff 3.97 s later. What is the height H of the cliff in m? What is the maximum height reached by the arrow along its trajectory in meters? What is the arrow’s speed just before hitting the cliff in 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.
