Speed of a Sky Diver after a Jump


During her sky-diving lesson, Nicole jumps out of a plane with an initial upward velocity of $2.3 \space m/s$.

Assume that she is falling vertically at a constant acceleration of $7.3 \space m/s^2$ pointing downward.

What is the magnitude (in m/s) of Nicole's velocity $3.2 \space s$ after she jumps out of the plane?
