Question

efectuati urmatorul calcul:360km/h+7200m/h+1,2km/min+7,2km/s+180dm/min,exprimand rezultatul in m/s.URGEEENTTT,DAU COROANAA​

Answer 1

Răspuns:

SI

360km/h=100m/s

7200m/h=*aproximativ*= 2m/s

1,2km/min= 20m/s

7.2km/s = 7200 m/s

180dm/min = 0.3 m/s

Rezolvare

v = 360km/h+7200m/h+1,2km/min+7,2km/s+180dm/min =>

v=100m/s+2m/s+20m/s+7200m/s+ 0.3 m/s =

7322.3 m/s

Raspuns: v =7322.3m/s
