A spacecraft starts from rest, and makes a journey to a destination 252000 km from its starting point. It does so by accelerating at a constant rate of 6.93 m/s^2 up to the midpoint of the journey, and then decelerates at the same constant rate of 6.93 m/s^2 for the second half of the journey, ending at rest. How long did the entire journey take? 1 2 hr 22 min 2 10 hr 6 min 3 5 hr 3 min 4 3 hr 21 min
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.
