Two arrows are shot vertically upward. The second arrow is shot after the first one, but while the first is still on its way up. The initial speeds are such that both arrows reach their maximum heights at the equal instant, although these heights are different. Assume that the initial speed of the first arrow is 25.0 m/s and that the second arrow is fired 1.20 second after the first. Compute the initial speed of the second arrow.
