4. A car starts from rest and accelerates at the rate of 2ms" for 5 seconds. It maintains t velocity for another 5 seconds. It eventua undergoes a uniform deceleration and fina come to rest after further 5 seconds. a) Draw the velocity-time graph for the journey. b) Find the acceleration and deceleration respectively c) Find the total distance travelled during each stage. -2 d) Find the average velocity over the entire period.
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.
