MOTION IN DIMENSION Solve the following and explain your solution. 1. Mariella is running at a constant speed 0f 6.19m/s when she feels exhausted slowing down at a constant rate of 3.8m/s^2 until she rests. How long will it take her to stop? 2. A 1.7-m gunman field a bullet directly above his head at a speed of 90m/s. What is the maximum height the bullet can reach before it hits the ground. 3. Cyrus became angry with his defective phone that he threw the mobile phone down the cliff at a speed of 5.16m/s. What will be the mobile phone's velocity before it hits the ground if the is 20 meters high?
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.
