Speed Wrench

physics help please...?

A wrench falls out of the gondola of a balloon that is 470 m above the ocean. The acceleration of gravity is 9.8 m/s2 . Assuming negligible air resistance, what was the wrench’s speed as it hit the water? Answer in units of m/s.

speed is:
v = sqrt(2 * g * h) = sqrt (9219) = 95.979...m/s
