1. Prędkość p km/h wyraź w m/s .
2.Prędkość a m/s wyraź w km/h proszę o rozwiązanie daje naj
p*1000/3600 [m/s]
am/s=a /0,001km/1/3600h=a 3600*o,oo1km/h=3,6akm/h
1 km = 1000 m
1 m = 0,001 km
1 h = 3600 s
1 s = 1/3600 s
1.
p km/h = p*1000m/3600s = p*0,2(7) m/s ≈ p*0,3 m/s
2.
a m/s = a*0,001km/(1/3600)h = a*3,6 km/h
