KINEMATIKA• Gerak Lurus
GLBB
V₀ = 0 (diam)
a = 3 m/s²
a][ Jarak yang ditempuh kereta (S) setelah t = 2 s
S = V₀ t + ½ a t²
S = 0 + ½ • 3 • 2²
S = 6 m ✓
b][ Kecepatan kereta (Vₜ) setelah t = 4 s
Vₜ = V₀ + a t
Vₜ = 0 + 3 • 4
Vₜ = 12 m/s ✓
c][ Kecepatan kereta (Vₜ)
setelah menempuh jarak S = 36 m
Vₜ² = V₀² + 2 a S
Vₜ² = 0 + 2 • 3 • 36
Vₜ² = 6 × 36
Vₜ = 6√6 m/s ✓
