After a big snowfall, you take your favorite rocket‑powered sled out to a wide field. The field is 209 m across, and you know that your sled accelerates at a rate of 3.25 m/s^2 when the rocket is on. a) How much time will it take the sled to cross the field starting from rest, assuming the rocket is on the whole time in seconds? b) How fast will the sled be moving when it reaches the other end of the field in m/s? c) How fast will the sled be moving when it is halfway across the field in m/s
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.
