Odpowiedź:
s1=3 m
t1=1 s
-----------------
s3=5s1=5*3=15 m
albo
a=2s1/t1^2=2*3/1=6 m/s^2
v(2)=at=6*2=12 m/s
s(3)=at^2/2=6*3^2/2=27 m
s(2)=6*2^2/2=12 m
s3=s(3)-s(2)=27-12=15 m
Wyjaśnienie:
s(t)=at^2/2
s(1)⇒t^2=1^2=1
s(2)⇒2^2=4;s2=s(2)-s(1)=4-1=3
s(3)⇒3^2=9; s3=9-4=5
s(4)⇒4^2=15; s4=15-9=7
itd
drogi w kolejnych sekundach to kolejne liczby nieparzyste
1,3,5,7,....s2=3s1; s3=5s1 itd..
