Extreme-sports enthusiasts have been known to jump off the top of El Capitan, a sheer granite cliff of height 910 mm in Yosemite National Park. Assume a jumper runs horizontally off the top of El Capitan with speed 5.0 m/sm/s and enjoys a freefall until she is 150 mm above the valley floor, at which time she opens her parachute. Part A How long is the jumper in freefall? Ignore air resistance. Part B It is important to be as far away from the cliff as possible before opening the parachute. How far from the cliff is this jumper when she opens her chute? Express your answer using two significant figures.
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.
