2.) A subway train starts from rest at a station and accelerates at a rate of 2.50 mls for 15.90 seconds. H then runs at a constant speed of 35 seconds and then slows down at a rate of 4.50 ml s until it sto ps at the next station? 0) what is the speed of the train to finish th before It starts slo wing. down? Given: Solution Vi 0mls a: 2.50 m Is? At 15-90 seconds Ve: (o mls) + (2.50.mls²)(15.90 s). 39.75 m Is Requined: #: ? Equation: Vf = Vi + a At. b) How long did it take the frain to finish the trip from one station to the other ?
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.
