Explicación:
R = 50 cm
v= 10 cm/s
a) Velocidad angular
v = ω x R
V
ω = ------
R
10 cm/s
ω = ------------- = 0.2 rad/seg
50 cm
b) aceleración centrípeta.
V²
Ac = ------
(10 cm/s)²
Ac = ----------------
100 cm²/s²
Ac = ----------------- = 2 cm/s²
Ac = 2 cm/s²
cm 1 m
2 ---------- x ----------- = 0.02 m/seg
seg 100 cm
C) el periodo y la frecuencia
2 π 6.28 rad
T = -------- = -------------------- = 31.4 seg
ω 0.2 rad/seg
1 1 revol
f = ----- = --------------- = 0.0318 revol/seg = 0.032 Hz
T 31.4 seg
d) número de vueltas que dará en 10 seg.
t 10 seg
n = ---------- = ----------------- = 0.318 vueltas = 0.32 vueltas
