2. Sketch a distance-time graph of the situation explained below in the blank coordinate grid. A person begins to run and travels 30 meters in the first 10 seconds of his trip. He then decides to stop because running for 10 seconds was way too difficult. He only rests for 5 seconds. He then runs with a velocity of 2 m/s for 10 more seconds. He then turns around and jogs back to his original position, at a non-constant rate of change, arriving there at t=30 seconds. 450 Distance (m) 40 30 20 10 0 5 10 15 20 25 a. Calculate the average velocity of the person for the first 10 seconds of their trip. b. Would it be correct if the line from [0,10] was curved? Explain. 30 c. Calculate the average velocity of the person over the first 15 seconds of their trip. Time (s)
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.
