An arrow is shot vertically upward with an initial speed of 25 m/s. When it’s exactly halfway to the top of its flight, a second arrow is launched vertically upward from the same spot. The second arrow reaches the first arrow just as the first arrow reaches its highest point.   What is the launch speed of the second arrow?                         What maximum height does the second arrow reach?
