# Degree of raindrop

A train travels due south at $$30 \text{ m/s}$$ (relative to the ground) in a rain that is blown toward the south by the wind. The path of each raindrop makes an angle of $$70 °$$ with the vertical, as measured by an observer stationary on the ground. An observer on the train, however, sees the drops fall perfectly vertically. Determine the approximate speed of the raindrops relative to the ground.
