Ben Torres decides to run a race against... well... himself. It's COVID world, so things are different. Anyways, he wants to run a 100 m dash. He starts from rest and accelerates at a rate of 3.4 m/s2 while covering a total of 11 m. a) How fast is he going after he runs the first 11 m? b) How long does it take him to run the first 11 m?
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.

a) How fast is he going after he runs the first 11 m?
b) How long does it take him to run the first 11 m?
Solution:
Given that
distance s = 100 m
a =3.4 m/s2
