4. A man arrives at the railroad station nearest his country ho me an hour and 5 minutes before the time at which he had ordered his driver to meet him with his car. He starts to walk at the rate of 4 mph and m eets his car when it has traveled 8 m iles. It turns back and takes him the remainder of the way home, where he arrives just I D minutes ahead of the ti me he had originally planned to get there. Find the distance fro m the station to his home. Assume no waiting ti me on the part of his driver.
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.
