vi 4. A car is traveling at 20 m/s when it pulls out to pass a truck that is traveling at 18 m/s. The car accelerates at 2.0 m/s² for 7.0 s. Pt (a) What distance does the car travel during the period of acceleration? [Ans: 1.9 x 10²m] a (b) What is the car's speed at the end of the period of acceleration? [Ans: 34m/s] vf (c) If the car was originally 8.0 m behind the truck when it pulled out to pass, how far in front of the truck is the car right after acceleration? [Ans: 55m]
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.
