Passo 1
∆s = Vt – gt²/2 g = 9,8 m/s²
8 = 0 – 9,8t²/2 ∆s = 8 m
4 = -9,8t²
-4/9,8 = t² t = √0,408 t = 0,63s
Passo 2
V = Vo – gt t = 0,63 s
V = 0 – 9,8 * 0,63
V = 6,26 m/s
Passo 3
V² = Vo² + 2g∆s Vo = 3062,5 m/s
0² = 3062,5² - 2 * 9,8∆s g = 9,8 m/s²
- ∆s = -3062,5²/2 * 9,8
∆s = 478515,62 m
Passo 4
∆s = (Vo + V)t/2 ∆s = 478515,62 m
8478515,62 = 3062,5t/2 Vo = 3062,5 m/s t = 957031,25/3062,5 V = 0 m/s t = 312,5 s
Etapa 3
Passo 1
∆s = Vt – gt²/2 ∆s = 1000 pés = 304,87 m
304,87 = 0t – 9,8t²/2 V = 0
609,75 = -9,8t² g = 9,8 m/s² t = √62,22 t = 7,88 s
Passo 2
∆x = (Vo cos βo)t Vo = 111,11 m/s
∆x = (111,11 cos βo) * 7,88 t = 7,88 s
∆x = 875,54 m cos βo = 0 = 1
Passo 3
Vx = Vo cos βo cos βo = 0 = 1
Vx = 111,11 cos βo Vo = 111,11 m/s
Vx = 111,11 m/s sen βo = 0 = 0
Vy = Vo sen βo – gt
Vy = 111,11 sen βo – 9,8 * 7,88
Vy = 0 – 77,22
Vy = -77,22 m/s
Passo 4
V² = Vx² + Vy² Vy = -77,22 m/s
V = √111,11² + 77,22² Vx = 111,11 m/s
V = 135,3 m/s
