2. A toy rocket launches from the ground (starting from rest) and rises straight up with an acceleration of 4.0 m/s. The rocket maintains this acceleration until it runs out of fuel at an altitude of 530 m. After running out of fuel, the acceleration of the rocket is the acceleration due to gravity, pointing straight downward. (a) What is the rocket's velocity when it runs out of fuel? (b) How long does it take the rocket to reach this point? (c) What is the maximum altitude reached by the rocket?
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.
