An automobile traveling 95 km/hkm/h overtakes a 1.40 kmkm -long train traveling in the same direction on a track parallel to the road. A) If the train's speed is 75 km/hkm/h, how long does it take the car to pass it in minutes? Express your answer to two significant figures and include the appropriate units. B) How far will the car have traveled in this time? Express your answer to two significant figures and include the appropriate units. C) How long does it take the car to pass the train if the car and train are traveling in opposite directions in minutes? Express your answer to two significant figures and include the appropriate units
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.
