rocket starts from rest on the ground and then accelerates at 39.2 m/s2 [up] for 5.0 s. T/I (a) Calculate the velocity of the rocket when the engines stop firing after 5.0 s. (b) Calculate the maximum height of 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.
A toy rocket starts from rest on the ground and
then accelerates at 39.2 m/s2 [up] for 5.0 s. T/I
(a) Calculate the velocity of the rocket when the
engines stop firing after 5.0 s.
(b) Calculate the maximum height of the rocket.
(c) How long will it take the rocket to hit the ground
from rest at the maximum height and initial rest?
