Predkość płyty CD wynosi 100m/s, promien plyty= 6cm
Oblicz predkość kątową oraz częstotliwość danej płyty
dane:
v = 100 m/s
r = 6 cm = 0,06 m
szukane:
ω = ?
f = ?
v = ω·r /:r
ω = v/r = 100m/s/0,06m = 1666,(6) rad/s
ω ≈ 1666,7 rad/s
============
v = 2πrf /:2πr
f = v/2πr = 100m/s/(2*3,14*0,06m) = 265,39/s
f ≈ 265,4 Hz
