3. An aircraft leaves the point (5, 7, 0) at 12:00 and travels in the direction 4i + 8j + k with speed 450 km/h. All distances are measured in km and time is measured in hours after 12:00. a. Find its velocity vector b. Find its position at time t At 12:15, the aircraft stops climbing and its velocity is now given by 250i + 350j km/h. c. Find its position at time t for t > 0. 25 d. Find the angle between the initial velocity and the new velocity
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.
