Unit 1: Kinematics Ahmed and Khalid are having a 100m race from start to finish. Ahmed gives Khalid a 25m head start (he waits until Khalid is 25m away before starting). Khalid travels at a constant velocity of 5 m/s. Assuming that Ahmed accelerates uniformly from rest at 0.75 m/s², does he pass Khalid before the finish line? If so, where? If not, how much longer does Khalid take to finish? (explain your reasoning)
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.
