Exercise 2. A schoolbus accelerates for 16 s with 0.9 m/s 2, after that it drives for 50 s with constant velocity and eventually comes to a halt by braking with -0.6 m/s 2. a) Sketch the graph of the position s(t), the velocity v(t) and the acceleration a(t). b) Determine the covered distance d, the average velocity v and the braking time tb.
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.
