a)0,5m/min la patrat , 120cm/min la patrat , 100km/h la patrat , 320 mm/s la patrat.

Dau coroana !!!

Answer 1

Trebuie convertit la m si s.

1min=60s

1min^2=3600s^2

1h=3600s

1h^2=3600^2 s^2

1cm=0.01m

1mm=0.001m

0.5m/min^2=0.5/3600 m/s^2

120cm/min^2÷1.2/3600m/s^2

100km/h^2=100×1000/(3600^2) m/s^2

320mm/s^2=0.32m/s^2

Calculele le faci tu. Succes!
