1. The problem statement, all variables and given/known data
What is the time of flight of a golf ball? The Vi=40 m/s, the angle is 35 degrees, and the mass is .046kg.

2. Relevant equations

I'm assuming I need to use $$v = v_0 + a t$$ but I don't know the final velocity or how to get it.

3. The attempt at a solution
I'm totally stuck

Consider the vertical direction. How long does it take to reach its maximum point (where vertical velocity is 0)? How long does it take to come back down again?
