How to calculate ballistic trajectories

[tranhoangha1989 (hatran)]

Hi everyone,
I want to calculate and draw ballistic trajectories in Cocos Creator 3.0
For example, i have a ball at (0,0,0) and i want to applyImpulse on rigidBody to move ball to (50, 20, 10).
Please help me how to do this.

I opened it with Cocos Creator 3.0 but only show black screen, maybe it written in Javascript.
