An automobile starts from rest and reaches a speed of 42 m/s in 15 seconds. The acceleration increases from zero, uniformly with time in the first 9 seconds after which is remained constant. 1.) Compute the acceleration of the car after 9 seconds 2.) Compute the velocity of the car after 9 seconds? 3.) Determine distance traveled by the car after 15 seconds?
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.
