A model rocket fired from the ground ascends with a constant upward acceleration. A small bolt is dropped from the rocket 1.0s after the firing and the fuel of the rocket is finished 4.0 s afrer the bolt is dropped. Air- time of the bolt is 2.0s. Acceleration of free fall is 10m/s^2. Which of the following statements is/are correct? a) acceleration of the rocket while ascending on its fuel is 8m/s^2 b) Fuel of the rocket was finished at a height 100m above the ground. c) maximum speed of the rocket during its upward flight is 40m/s d) Total air time of rocket is 15s
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.
