Hello guys! I am trying to implement Projectile Trajectory in my game so I can predict where a ball will be after addForce. What I want is to compute the t time in which I get to an s displacement using this formula:

**y = viy • t + 0.5 • g • t^2**

(equation for vertical displacement for an angled-launched projectile)

The problem is that something does not work right for me, and I am confused about Vi.y which should be initial velocity. Can’t I just use the rigidbody.velocity.y in the moment of launch as initial velocity? I also tried computing force * sin(angle at launch) but I also won’t get the right results.

Also, A a test I tried to log in updated this:

```
Debug.Log(v.y * t+ Physics.gravity.y * t * t);
```

where t increases with fixedDeltaTime, but the resulting dispersions are not right…

Ex: ball starts at y = 1, when ball is at 0 I get a value smaller then -1 (like -3)
