L=6.0 m 1. The first section of the motion is a ramp with no friction; riders start at rest and accelerate down the ramp. 2. The second section of the motion is a circular segment that changes the direction of motion; riders go around this circular segment at a constant speed and end with a velocity .. that is horizontal. 0 = 45°/ /r= 1.5 m h=0.60 m 3. The third section of the motion is a parabolic trajectory through the air at the end of which riders land in the water. FIGURE P3.84
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.
A rider on a water slide goes through three different kinds of motion, as illustrated is shown. Use the data and details from the figure to answer the following question.
Suppose the designers of the water slide want to adjust the height h above the water so that riders land twice as far away from the bottom of the slide. What would be the necessary height above the water?
A. 1.2 m B. 1.8 m C. 2.4 m D. 3.0 m
