An Olympic sprinter competes in 100m dash. The runner accelerates from rest to maximum speed at a constant rate during the first 3s, and completes the race in 10.01s. a. What are the accelerations and maximum speed of the sprinter? x m/s² X m/s b. The sprinter wants to estimate the time to run a 200m dash. Assuming the same acceleration and maximum speed as in part (a), determine the time required to complete the race. The present world record (as of 2013) is 19.19s. THINK ABOUT IT:Do the assumptions made for this race seem plausible? XS
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.
