While riding in a hot air balloon, which is steadily descending at a speed of 2.69 m/s, you accidentally drop your cell phone. (a) After 3.00 s, what is the speed of the cell phone? v = m/s (b) How far is the cell phone below the balloon after this time? d = m (c) What are your answers to parts (a) and (b) if the balloon is rising steadily at 2.69 m/s? v = m/s d = m
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.

| v | = | m/s |
(b) How far is the cell phone below the balloon after this time?
| d | = | m |
(c) What are your answers to parts (a) and (b) if the balloon is rising steadily at 2.69 m/s?
| v | = | m/s |
| d | = | m |
