Ruch krzywoliniowy, siła dośrodkowa. Zadania w załączniku ;)
1.
T= 24*3600=86400 s
r=6,387*10^6 m
v=ωr=2πr/T
v= 2*π*6,387*10^6/86400=464,5 m/s
2.
m=2 kg
F=10 N
r=0,5 m
F=m*an
an=v^2/r=ω^2r
F=mω^2r
ω= (F/mr)^(0,5)
ω= (10/(2*0,5))^(0,5)=3,16 rad/s
3.
Th= 12h= 12*3600=43200 s
rh1=10 cm=0,1 m
rh2=5 cm=0,05 m
ωh= 2πf=2π/T
ωh= 2*π/43200=1,45*10^-4
v1=ωr= 1,45*10^-4*0,1=1,45*10^-5 m/s
v2=1,45*10^-4*0,05=7,25*10^-6 m/s
