d = 100 m
t = 12 s
a =?
Vf = ?
d₁ = ? t = 1 s
d₂ = ? t = 12 s
Formula
a = Vf² - V₀² / 2 d
a = Vf² / 2 d
2 a d = Vf²
Vf = √ 2 a d = 2 (1.388 m/s²)(100 m) = 16.66 m/s
d = V₀ t + a t² / 2
d = a t² / 2
2 d = a t²
a = 2 d / t² = 2 (100 m) / (12 s)² = 1.388 m/s²
d₁ = a t² / 2 = (1.388 m/s²)(1 s)² / 2 = 0.694 m
d₁₂ = a t² / 2 = (1.388 m/s²)(12 s)² / 2 = 99.93 m
