Solution: the whereabouts of speed and quality of related objects general g = 10 for each square of the second
under Vt = Vo + gt (Free Falling initial velocity Vo = 0) H = 1/2gt * t
20 = 0.5 * 10 * t * t solution of t = 2s
under Vt = gt = 10 * 2 = 20m / s
50 = 0.5 * 10 * t * t t = Solution No. 10
Vt = root gt = 10 * 10 = 10 times the radical roots of 10
A: The landing speed was 20m / s
and 10 times the roots and 10m / s.
