2^2+3.46^2=15.97
sqrt(15.97)
3.99 m/s
tan^-1(3.46/2)= 59.97 degrees
3.99m/s @ 59.97 degrees'
sqrt(15.97)

You've used the initial vertical velocity. As a result, you've recalculated the initial angle and overall speed.akshajkadaveru said:2^2+3.46^2=15.97

You posted the correct final vertical velocity in post #27. Just use that instead of 3.46 in your calculation in post #36.akshajkadaveru said:ARGHGHGHH! so what i JUST did was wrong but what will my X and Y value things be then ?
I meant 28.akshajkadaveru said:i didn't post anything on 27
Where are you getting 1m/s from for the x direction?akshajkadaveru said:so is it... 1^2+1.44^2=whatever
sqrt(whatever)= ______ @ tan^-1(1.44/1)?
will that be my answer?
No, you can't add a velocity to a length, or a velocity-squared to a length-squared. It makes no sense.akshajkadaveru said:oh... i thought that't just the length of how far the thing went... how do i get that then >?
