A balloon is rising at 19 m/s when its passenger throws a ball straight up at 21 m/s. How much later does the passenger catch the ball?

2. Relevant equations

Don't know relevant equations. except v(t)=vot-0.5(9.8)t^2 but I don't think that works.

I've attempted this question 4 different ways and times. The answer isn't 4.0816 or 8.1632.

Please help, any help would be appreciated.
