A ship moves through water with two forces acting on it. One is a forward thrust through the water on the propeller of 1,875 N, and the other is a resistive force due to the water around the bow of 1,200 N. (a) What is the acceleration of the 1,300-kg boat? (b) If he starts from rest, how far will the boat move during 22.5 s? (c) What will its velocity be at the end of that time?
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.
