Math 216 Homework webHW3, Problem 4 A person leaps from an airplane 9500 feet above the ground and deploys her/his parachute after 17 seconds. Assume that the air resistance both before and after deployment of the parachute results in a deceleration proportional to the person's velocity, but with a different constant of proportionality. Before deployment, take the constant to be 0.14, and after deployment use the value 1.6. (The acceleration due to gravity is 32.2ft/sec2. Note also that the constants of proportionality given are p = klm, not k.) How fast is the person going when the parachute is deployed? speed = How high off the ground is the person when the parachute is deployed? height= Approximately (to one decimal place) how long after the parachute deploys does the person reach the ground (give your answer in seconds)? time 2

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.
