1-D motion with constant acceleration (comprehensive example)

Example 1-D motion problem involving constant acceleration (finding acceleration and displacement of an object given the initial and final velocities and the corresponding time interval). Each part is solve multiple ways in order to illustrate all of the commonly used equations for 1-D constant acceleration kinematics. Commentary includes a discussion of choice of coordinate system, the difference between speed and velocity (and between distance and displacement), and the implications of an alternative scenario in which the acceleration is NOT constant. 0:00 Introduction 0:37 Problem statement 1:07 Choose coordinate system 1:37 Calculate acceleration 5:05 ... (Calculate acceleration, 2nd way) 7:32 Calculate displacement 7:51 ... (displacement, 1st way) 13:04 ... (displacement, 2nd way) 15:15 ... (displacement, 3rd way) 17:37 Closing remarks 17:43 ... [#1] what if we chose LEFT to be +x direction? 19:31 ... [#2] speed vs velocity, distance vs displacement 23:35 ... [#3] what if accel. was NOT constant?
