If I throw a ball straight up to a height h with velocity v and it takes the ball time t to go up and back to my hands, by how much would time increase or decrease if gravity on earth where changed from g to g/6?

2. Relevant equations

v = a*t

3. The attempt at a solution

I wanted make sure what I am thinking was correct. I thought about this problem as a projectile problem and said that t = (v*sin(theta))/a, where "a" is acceleration. Now since the ball was thrown straight up, I made sin(theta) to sin(90). So the problem comes out to be t=v/a, and since "a" decreases by a factor of 6 that means time increase by a factor of 6. Would this reasoning be the correct way to do it?
