Question

4. Efectuati următoarele transformări
a) 60 km/h = ?m/s,
b) 25 km/h = ? m/s,
c) 180 km/h = 2 m/s
d) 30 m/s = ? km/h
e) 25 m/s = ? km/h,
f) 340 m/s = ? km/h

Answer 1

Răspuns:

..a) 60km/h= 16,6

b).25km/ h= 6,9m/s

c)180km/h= 50m/s

d) 30m/s= 108km/h

e)25m/s=90 km/h

f)340m/s= 1124km/h

1ora = 36000 secunde = 1 km =1000 m

60km = 60 1000m/3600 s= 1000 m/ s=16,(6)m/s
