Free fall problem with an extra variable

[mwhowell]

Homework Statement

Jane is riding in a hot air balloon that is rising vertically at a constant speed of
3m/s over a lake. She reaches out and drops a rock from the balloon when the
distance from the rock to the water is 50m. Use g=10m/s2, and let the up
direction be positive.
How long after Jane drops the rock will it splash into the water?

Homework Equations

The Attempt at a Solution

I know how to do this problem but I was wondering if the fact that Jane is traveling upwards has an effect on the free fall of the rock.

It just means the rock has an initial velocity of 3m/s upward. It's really a projectile problem. It's the same thing as standing on a platform 50m above the ground and throwing the rock straight up.
