For the ball in exercise E1, a. Through what distance does the ball fall in the first 0.6 seconds of its flight? (Assume g = 10 m/s^2.) b. How far does it fall in the first 1.2 seconds of its flight?
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.
For the exercises in Chapter 3, use the approximate value of g = 10 m/s2 for the acceleration due to gravity.
E1. A steel ball is dropped from a diving platform (with an initial velocity of zero). Using the approximate value of g = 10 m/s^2, a. What is the velocity of the ball 0.6 seconds after its release? b. What is its velocity 1.2 seconds after its release?
E2. For the ball in exercise E1, a. Through what distance does the ball fall in the first 0.6 seconds of its flight? (Assume g = 10 m/s^2.)
b. How far does it fall in the first 1.2 seconds of its flight?
