Pendulums - AP Physics 1 Quiz

A student studying Newtonian mechanics in the 19th century was skeptical of some of Newton's concepts. The student has a pendulum that has a period of 3 seconds while sitting on his desk. He attaches the pendulum to a ballon and drops it off the roof of a university building, which is 20m tall. Another student realizes that the pendulum strikes the ground with a velocity of $12$\frac{m}{s}$$ . What is the period of the pendulum as it is falling to the ground?

Neglect air resistance and assume $g=10$\frac{m}{s^2}$$
