A model rocket blasts off and moves upward with an acceleration of 13m/s^2 until it reaches a height of 27m, at which point its engine shuts off and it continues its flight in free fall. a) What is the maximum height attained by the rocket? b) What is the speed of the rocket just before it hits the ground? c) What is the total duration of the rocket's flight?
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.
