1. A train leaves the station on a 50 km commute. The train must make a 60-second stop every 1.0 km to pick up and drop off passengers. The train accelerates at 2.0 m/s2, then cruises at 90 km/h, and then decelerates at 5.0 m/s2 between stops. (a.} How many stops does the train make? (b.} How long does it take for the train to get from one stop to the next? (c.} What is the total time for the entire commute?
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.
