Problem viewing java?Add http://www.phy.ntnu.edu.tw/ to exception site list
If java program did not show up, please download and install latest Java RUN TIME

This is an EJS 4 generated simulation to illustrate projectile motion.

Vi is the initial speed when the firework were shot from the ground.
Vf is the velocity relative to the center of mass when it spread out.

Do you know why the sound is delayed?
Will you be able to find out the distance between you and the place where the firework were fired from the delay of the sound?
Do not forget to TURN your speaker volume UP to hear sound effects.
