Question

A wrench falls out of the gondola of a balloon
that is 830 m above the ocean.
Assuming negligible air resistance, what
was the wrench’s speed as it hit the water?
The acceleration of gravity is 9.8 m/s2 .
Answer in units of m/s

Answer 1

V = sqrt(2*g*H)

g = 9.8 m/s^2
H = 830 m

Use the above formula for the final velocity, V.

Answer 2
