rocket, on an unknown planet, launches straight upward. Starting from rest, the rocket accelerates until it reaches 25 m/s then maintains that velocity until its boosters shut off. It eventually falls back to the planet.
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.

ASSUME:
-
Starting at t = 0, the rocket accelerates upwards a total distance of 10 m, where it reaches an instantaneous velocity of 25 m/s
-
The moment it reaches an instantaneous velocity of 25 m/s, it travels 30 m upward at a constant speed, then the engines cut off.
-
The moment the engines cut off: the rocket is in free fall
From the time it initially launches (t = 0) to the time it lands back on the planet is 7 s
-
The acceleration due to gravity is constant on this planet. HOWEVER you may not assume g = 10 m/s2
-
Air resistance is negligible
