Ejs Open Source 2 mass rolling on incline plane Model Java Applet by Fu-Kwun Hwang
a solution to the problem given here http://www.phy.ntnu.edu.tw/ntnujava/index.php?topic=2309.0

Embed a running copy of this simulation

Embed a running copy link(show simulation in a popuped window)
Full screen applet or Problem viewing java?Add http://www.phy.ntnu.edu.tw/ to exception site list
Press the Alt key and the left mouse button to drag the applet off the browser and onto the desktop. This work is licensed under a Creative Commons Attribution 2.5 Taiwan License
  • Please feel free to post your ideas about how to use the simulation for better teaching and learning.
  • Post questions to be asked to help students to think, to explore.
  • Upload worksheets as attached files to share with more users.
Let's work together. We can help more users understand physics conceptually and enjoy the fun of learning physics!

changes:
fixed relationship
v1 = Math.sqrt(vx1*vx1+vy1*vy1);
v2 = Math.sqrt(vx2*vx2+vy2*vy2);
texttime = " t = " + _view.format(t,"0.00");

add title Ejs Open Source 2 mass rolling on incline plane Model Java Applet
add author Fu-Kwun Hwang remixed by weelookang@gmail.com
add data processing for student to analyze like in tracker

07 October 2011
activate x vs t and v vs t


09 October 2011
debug the t or fund a bug in the time calculation
add slider cta2degree
code is cta2degree = Math.toDegrees(cta2);
and on the slider add cta2 = Math.toRadians(cta2degree);


enjoy!
i didnt enable the answers, u still have a good chance to work hard to find out the answer yourself! Grin
