n an online viral video, a truck rolls down an incline and off a vertical cliff, falling into a river below. The truck starts from rest and rolls down the incline, which makes an angle of 18.0° below the horizontal, with a constant acceleration of 2.90 m/s2. After rolling down the incline a distance of 30.0 m, it reaches the edge of the cliff, which is 50.0 m above the river. (a) How much time (in s) does it take the truck to fall from the edge of the cliff to the landing point? (b) At the point where the truck lands in the river, how far is it horizontally from the edge of the cliff (in m)?
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.
