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.

5. An object is pushed along a rough surface and released. It slides for 10.0 s before coming to rest and
travels a distance of 20.0 cm during the last 1.0 s of the slide. Assuming the acceleration is uniform
