SMA KELAS 10
BAB : GERAK
Diketahui :
Vo = 5m/s
a = 6 m/s2
S1 = 10 m
Ditanyakan : Vt saat S2 = 60 m
Dijawab :
Jarak yg ditempuh selama mengalami percepatan :
S = S2 - S1
= 60 - 10
= 50 m
Jadi kecepatan saat S = 60 m adalah :
Vt² = Vo² + 2xa x S
Vt² = 5² + 2 x 6 x 50
Vt² = 25 + 600
Vt = √625
Vt = 25 m/s
