Problem 7.90 14 of 14 Stretchable ropes are used to safely arrest the fall of rock climbers. Suppose one end of a rope with unstretched length l is anchored to a cliff and a climber of mass m is attached to the other end. When the climber is a height l above the anchor point, he slips and falls under the influence of gravity for a distance 21, after which the rope becomes taut and stretches a distance x as it stops the Constants | Periodic Table тg 4ki mg Submit Previous Answers climber (see the fiaure(Fiaure 11) Assume a stretchy rope Figure < 1 of 1 v Correct -Fall begins Part B Anchor Assuming m = 89 kg , l = 8.8 m and k = 840 N/m , determine x/l (the fractional stretch of the rope) at the moment the climber's fall has been stopped.

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.
