Problem 2: A motorcycle is slowing down uniformly, with a constant acceleration. The motorcycle covers 1000 m in 80 sec. The motorcycle then covers the next 1000 m in 120 sec. a) What is the acceleration of the motorcycle? Answer: 0.042 m/sec² b) What is the initial speed of the motorcycle? Answer: 14.2 m/sec c) What is the final speed of the motorcycle? Answer: 5.8 m/sec t = 0 sec Vo Motorcycle At₁ = 80 sec ā x = 1000 m At₂ = 120 sec x = 2000 m x
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.
