A bullet is fired with an initial speed of 20 m/s at an angle of 30 degrees with horizontal. Ignoring air resistance. The time when the bullet reaches the highest point of its flight and the maximum heighth: O 0.2 sec, 1.25 m O 3.0 sec, 1.5 m O 0.7 sec, 1.4 m O 1.0 sec, 5.0 m
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.
