Questions 1. Knight P2.20 Ball bearings are made by letting spherical drops of molten metal fall inside a tall tower called a shot tower and solidify as they fall. (a) If a bearing needs 4.00 sec to solidify enough for impact, how high must the tower be? Use acceleration ao = g = -9.8 m/s². (b) What is the bearing's impact velocity? la. 1b. 2a. 2b. 2c. y 2. Knight P2.33 A particle moving along the x-axis has its position described by the function x(t) = 2t³ + 2t + 1, where x is in meters and t is in seconds. At t = 2.00 seconds what are the particle's (a) position, (b) velocity, and (c) acceleration? 80 m -40 m/s Yo, Vo= 0, to = 0 Answers to one significant figure 20 m 30 m/s 20 m/s² y = 0, V₁, t₁ = 4
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.
