A skiier is moving at a speed of 2.50 m/s when passing the starting line on a hill that initially has a 20.0° slope. After 32.0 m the hill becomes steeper with a slope of 30° for the next 32.0 m until the finish line which is at an elevation of 30.0 m below the starting point. Assuming there is no friction or air resistance, how fast is the skiier moving at the finish line?
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.
