Răspuns:
acceleratia in SI este exprimata prin m/s²
facem transformarile
1 min² = (60s)² = 3600 s²
1 h² = (3600s)² = 12960000 s²
120 cm = 1,2 m
100 km = 100000 m
320 mm = 0,32 m
a)
0,5m/min² = 0,5m/3600s² = 0,00013(8) m/s²
b)
120 cm/min² = 1,2m/3600s² = 0,000(3) m/s²
c)
100 km/h² = 100000m/12960000s² = 0,007716 m/s²
d)
320 mm/s² = 0,32 ²m/s
