Vo = 10 m/s
cos α = 3/5 → sin α = 4/5
t = 1 s
g = 10 m/s²
(X, Y) = ___?
X = Vo cos α t
X = 10 • 3/5 • 1
X = 6 m
Y = Vo sin α t - ½ g t²
Y = 10 • 4/5 • 1 - ½ • 10 • 1²
Y = 3 m
Posisi saat t = 1 s adalah (6, 3) m ✔️

Va = 30 m/s
Vb = 10 m/s
S = 160 m
Kecepatan relatif A terhadap B
Vab = Va - Vb
Vab = 30 - 10
Vab = 20 m/s
Waktu temu
S = Vab t
160 = 20 t
t = 8 s ✔️
