A sprinter starting from rest on a straight and level track is able to achieve a speed of 17 m/s in a time of 5.3 s. What is the sprinter's average acceleration? m/s2
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 sprinter starting from rest on a straight and level track is able to achieve a speed of 17 m/s in a time of 5.3 s. What is the sprinter's average acceleration?
m/s2
use v = u + a t
where v is final velocity
u is initial velocity
a is acceleration
t is time.
u = 0 m/s , v = 17 m/s , t = 5.3 s
