A car is moving at uniform acceleration. Its velocity after traveling for 2 seconds is 4m/s and is found 12 meters from where it started. If the car’s velocity at 5 seconds is 10 m/s, determine (a) the car’s acceleration, (b) its displacement at t = 5 seconds measured from its starting point and (c) its velocity at the start.
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.

and is found 12 meters from where it started. If the car’s velocity at 5 seconds is 10 m/s,
determine (a) the car’s acceleration, (b) its displacement at t = 5 seconds measured
from its starting point and (c) its velocity at the start.
