1.
vf = vi + gt
vf = 0m/s + 10m/s^2 * 1s
vf = 10m/s
h = (vi - vf /2) * t
h = (0 - 10m/s /2) * 1
h= 5 m
2.
vi = 28m/s
t = 1s
h= ?
g = 10m/s^2
h = vit + 1/2gt^2
h = 28m/s + 1/2 (10m/s^2)(1)^2
h = 33m
3.
vi = 120m/s
t = 20 s
g = 10 m/s^2
vf =?
vf = vi + gt
vf = 120m/s + (10m/s^2) (20s)
vf = 320 m/s
4.
vi = 5m/s
g = 10m/s^2
velocidad triplicada 125m/s
t = vf - vi/ g
t = 0m/s - 125m/s / 10m/s^2
t = 12.5
h = vit + 1/2gt^2
h = (125m/s)(12.5) + 1/2(10m/s^2)(12.5)^2
h = 1562.5 + 781.25
h = 2343.75
vf = vi + gt
vf = 0m/s + 10m/s^2 * 1s
