Okay, so here's a problem from a practice test:

"Suppose that a ball is thrown vertically upward from earth with velocity v, and returns to its original height in a time, t. If the value of g where reduced to g/6, then t would:

a) incr by 6

b) incr by 6^.5

c) decr by 6

d decr by 6^.5

Okay, so I narrowed it down to a & b, and I WAS going to pick a (the correct answer), but then of course I had to doubt myself and pick b.

I chose a at first using t = v/g. but then I switch to b, because I used h = .5at^2.

Now I'm confused. Both equations are valid for time, but why was the t = v/g correct for this problem?
