Adaptation of Mario Belloni's physlet problem to work as a calculated question within WebCT.
One dimensional motion.
Knowlege of one-dimensional kinematics.
This question looks for the java archive files in the webct_install_dirwebctuserclasses subdirectory (i.e.,
Text of Learning Exercise:
Mario's orgininal problem may be viewed at http://webphysics.davidson.edu/physletprob/ch8_problems/ch8_1_kinematics/kinematics_1.html. It involves two blocks with different motion parameters. A green block accelerates from rest, and an orange block moves at constant velocity. Both blocks start from the same point at t=0. The questions asks for the point at which the green block overtakes the orange block. The animation stops before this event occurs.
The modification utilizes the random parameter feature of the WebCT calculated question format. The advantage here is that you can allow unlimited attempts and encourage collaboration. Since the parameters are re-randomized on each attempt,
it is appropriate to report the correct answer after an incorrect submission.
