Jawaban:
1. 72 km
2. 10 m/s
3. 2 m/s²
Penjelasan:
1. Diketahui :
v = 10 m/s = 36 km/jam
t = 2 jam
Ditanya :
s = ?
Penyelesaian:
s = v × t
= 36 km/jam × 2 jam
= 72 km
2. Diketahui :
s = 15 km = 15.000 m
t = 25 menit = 1.500 s
v = ?
v = s/t
= 15.000 m/1.500 s
= 10 m/s
3. Diketahui :
Vo = 10 m/s
Vt = 30 m/s
t = 10 s
a = ?
a =
[tex] \frac{vt - vo }{t}[/tex]
= 30 m/s - 10 m/s / 10 s
= 20 m/s / 10 s
= 2 m/s²
note : kalau salah mohon dikoreksi
