A train is travelling with a velocity of 90 km/h. The brakes are applied at a rate of -0.4 m/s?. Calculate the velocity after 8 seconds, the time taken to stop and the distance travelled by the train during the braking period. ) The velocity of the train 8 s after the brakes are applied is m/s () The time taken to stop the train is (i) The distance travelled by the train during the braking period is
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.
