y shooting water from its rear, a squid can provide itself with jet propulsion. Suppose a squid launches itself vertically upward from rest with constant upward acceleration for 0.890 s and travels a vertically upward distance of 2.72 m. The squid then turns off its jets and continues its flight in free fall. (a) What is the magnitude of the squid’s acceleration during the time it is jetting? (b) How long does it take the squid to reach its maximum height while in free-fall after jetting? (c) What maximum height did the squid attain?
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.
