(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A ball is launched vertically up from the ground. The initial speed of the ball is 37.5m/s. How long does it stay in the air?

2. Relevant equations

The 5 kinematic equations

3. The attempt at a solution

I figured the final speed would be 0m/s, and used the formula vf=vi+a*t so 0=37.5+(-9.8)t

and got t=3.83s... I don't think that's right, and was wondering if someone could please help me out? Any help is appreciated. Thanks
