RECTILINEAR MOTION PROBLEM 4 A car starting from rest picks up at a uniform rate and passes three electric posts in succession. The posts are spaced 360 m apart along a straight road. The car takes 10 seconds to travel from the first post to the second post and takes 6 seconds to go from the second to the third post. Determine the following: a. Acceleration of the Car b. Velocity of the car when it reach the first post c. distance from the starting point to the first post. VI V₂ =10 sect=6 sec 360 m 360 m • V=V₂ + at S=V₁+ are no ® V² = V² + 2aS
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.
