In a woman's 100-m race, accelerating uniformly, Laura takes 2.00 s and Healan 3.00 s to attain thier maxiumum speeds, which they each maintain for the rest of the race. They cross the finish line simultaneously, both setting a world record of 10.4 second a) what is the acceleration of each sprinter? b) What are thier respective maximum speeds ? c) Which sprinter is ahead at the 6.00-s mark, and) what is the maximum distance by which Healan is behind Laura , and at what time does that occur?
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.
