At the instant a traffic light turns green a car moves with 25,920 km/h2. Another car moving at 54km/h passes the car. What is speed when the first car passes the other car?
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.
At the instant a traffic light turns green a car moves with 25,920 km/h2. Another car moving at 54km/h passes the car. What is speed when the first car passes the other car?
The initially the first car starts from rest.
The first car starts with a constant acceleration,
The second car passes by the first car with the velocity,
Let time t is required by the first car to meet the second car.
The distance covered by the first car is equal to the distance covered by the second car.
So the expression,
