A sprinter runs a 100 m dash in 12.0 s. She starts from rest with a constant acceleration az for 4.0 s and then runs with constant speed for the remainder of the race. Part A What is the value of az ? Express your answer with the appropriate units. ? Value m/s² az
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.
![**Problem Description:**
A sprinter runs a 100-meter dash in 12.0 seconds. She starts from rest with a constant acceleration \( a_x \) for 4.0 seconds and then continues to run at a constant speed for the remainder of the race.
**Question:**
*Part A*
What is the value of \( a_x \)?
Express your answer with the appropriate units.
