Answer 1

pregunta 58
a) h= (0.5)(9.8m/s^2)((3segundos)^2) = 44.1 metros
b) v = raiz (2)(9.8m/s^2)(150m) = 54.22 m/s
c) t = (25 m/s ) / (9.8m/s^2)  =   2.55 segundos
d) t = raiz  ((2)(300m)) / (9.8m/s^2) = 7.824 segundos

pregunta 59
a) vf = (8m/s) + ((9.8m/s^2)(3 segundos)) = 37.4 m/s
b) h = ((8m/s)(3seg)) + ((0.5)(9.8m/s^2)((3seg)^2)  = 68.1 metros
