An automobile starts from rest and accelerates from rest and accelerates at 5 m/s2 for a period of 4.0s. Find the: a. Displacement b. Velocity after 4.0 s c. The car stops accelerating and moves at a constant speed for 10s. What would be the absolute displacement at t = 14s?
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.
An automobile starts from rest and accelerates from rest and accelerates at 5 m/s2 for a period of 4.0s. Find the:
a. Displacement
b. Velocity after 4.0 s
c. The car stops accelerating and moves at a constant speed for 10s. What would be the absolute displacement at t = 14s?
d. At t = 14s, the car starts to break with an acceleration of -8m/s2 . How long will it take for the car to come to rest?
e. The entire displacement moved through by the car
