Diket: vo = 400 km/jam t = 15 menit = 0,25 jam a = 800 km/jam² Dit: s.....? s = vo.t + 1/2 at² s = 400 x 0,25 + 1/2 x 800 (0,25)² --> kl pakai kalkulator bs langsung hitung. s = 400 x 25/100 + 400 ( 25x10^-2)² s = 100 + 400 (625x10^-4) s = 100 + 4x10^2 (625x10^-4) s = 100 + 2500x10^-2 s = 100 + 25 s = 125 Km
vo = 400 km/jam
t = 15 menit = 0,25 jam
a = 800 km/jam²
Dit: s.....?
s = vo.t + 1/2 at²
s = 400 x 0,25 + 1/2 x 800 (0,25)² --> kl pakai kalkulator bs langsung hitung.
s = 400 x 25/100 + 400 ( 25x10^-2)²
s = 100 + 400 (625x10^-4)
s = 100 + 4x10^2 (625x10^-4)
s = 100 + 2500x10^-2
s = 100 + 25
s = 125 Km
