This PhysCast deals with one dimensional motion. An electric vehicle starts from rest and accelerates at a rate of 2.0 m/s2 in a straight line until it reaches a speed of 20 m/s. The vehicle then slows at a constant rate of 1.0 m/s2 until it stops. (a) How much time elapses from the start to the stop? (b) How far does the vehicle travel from start to stop?

PhysCasts are narrated screen video recordings explaining physics concepts and their application to problem-solving. They have been produced by Swinburne University of Technology's Faculty of Science, Engineering and Technology. The series is part of an ongoing collaborative research project to develop high quality resources and investigate the effectiveness of screencasts to support learning.
