(a) Show that time to reach the half-way point is 71% of the time to reach the finish line? (b) Now considering the velocities at the half-way point (Vhalf-way) and the finish line (Vinal), which of the following is correct? Explain. i. Vhalf-way = 0.5 * Vfinal ii. Vhalf-way = 0.71 * Vfinal
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 = 3 m/s2
d= 400 m = finish line
half-way = 200 m
