Question 6 The next few questions challenge you to figure out the acceleration due to gravity ( g) on various hypothetical alien planets. On Planet #1, you drop a stone from rest, 68.4 m above the ground, and the stone hits the ground 5.49 s later. What is the value of g on Planet #1? 1 24.92 m/s^2 2) 4.54 m/s^2 3. 2.27 m/s^2 4. 12.46 m/s^2 --/5 Question 7 funm the ground at a speed of 51.2 m/s. The projectile reaches a
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.
Given:
The initial speed of the object is 0 m/s.
The height of the object from the ground is 68.4 m.
The time taken by the object to reach the ground is 5.49 s.
