A small mailbag is released from a helicopter that is descending steadily at 1.40 m/s. After 4.00 s, what is the speed of the mailbag? How far is it below the helicopter?
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 small mailbag is released from a helicopter that is descending steadily at 1.40 m/s. After 4.00 s, what is the speed of the mailbag? How far is it below the helicopter?
Given value---
- initial speed = 1.4 m/s.
- time = 4 sec.
We have to find---
- what is the speed of the mailbag?
- How far is it below the helicopter?
