Question

1.przelicz 80m/s na km/h
2.
a=4m/s do kwadratu
t=3min
s=? - wynik w km

Answer 1

1.
80 * 36km/10h = 288km/h
2.
s = a*t do kwadratu / 2
s= 4m/s kwadrat * (180s)kwadrat / 2
s= 64800m=64.8km

Answer 2

1. 80 razy 0,001/ 1/3600=
80 razy 0,001 razy 3600=288km/h

2. a=4m/s do kwadratu
t=3min=180s
s=at kwadrat/2
s=4 razy 180 do kwadratu/2
s=4 razy 32400/2
s=129600/2
s=64800m=64,8km
