Leg 1 What is the final velocity and position of a freight train that accelerates at a rate of 0.0700 m/s² for 4.00 minutes, starting with an initial velocity of 2.00 m/s? (a) • Using the notation Ax=x-x for displacement, x for final position, xo for initial position, v for final velocity, vo for initial velocity, a for acceleration, and t for time, determine what quantities are known and what quantities are unknown. • Enter the values of some known quantities below. • Make sure you account for the signs of the vectors using the coordinate system in Part 1. Enter to 3 significant figures. Enter with correct signs. m/s Vo = m/s² a = t= (b) Is the motion of the freight train one with constant velocity or constant acceleration? This will help you choose the correct equations of motion. (c) Choose an appropriate equation of motion from List 1 to calculate the final velocity of the train after 4.00 minutes. List 1 Ax= vt Δx = (vo + v) 2 S t v=V₁ + at ✓²=²+2a4x
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.
