A speedboat starts from rest and accelerates at +2.34 m/s2 for 7.87 s. At the end of this time, the boat continues for an additional 5.16 s with an acceleration of +0.368 m/s2. Following this, the boat accelerates at -0.729 m/s2 for 5.78 s. (a) What is the velocity of the boat at t = 18.81 s? (b) Find the total displacement of the boat
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.
