The follwing applet is Quiz: Do you know when two particles have the same horizontal speed?
Created by prof Hwang modified by Ahmed
Original project Quiz: Do you know when two particles have the same horizontal speed? (http://www.phy.ntnu.edu.tw/ntnujava/index.php?topic=714.0)

Click Play to start the simulation. Enter the time when you think those two particle have the same HORIZONTAL speed. (Enter into the text field and the answer will be shown).
You can change the initial velocity for both particle with your mouse (drag the RED arrow).
The horizontal velocity for the top one should be larger than the lower one.
The top one will move with constant velocity, while the second will need to move up the hill (with constant deceleration a=-g*sinθ)
You can also drag the yellow box to change the height of the slope.
Two traces shows X(t) for both particles.  Try to find out the answer from those two curves.

But I can't view the video and even the picture is too small.  :(

Hi Tara,

Actually not video is an EJS java simulation. are you sure that Java already installed in your system, check it and try again.

Good luck!
