Question

un auto recorre una pista circular de 840 metros de radio y da 24 vueltas cada 8 minutos calcula
periodo del movimiento
frecuencia
velocidad lineal
velocidad angular
aceleracion centripeta

Answer 1

Los datos son:
R = 840m
n = 24
t = 8min = 480s
T =?  f= ? v=? ω= ? ac=?
                                              T = t/n
                                              T = 480/24
                                              T = 20s
                                              f = 1/T
                                              f = 1/20s
                                              f = 0,05 Hz
                                              ω = 2π/T
                                              ω = 2π/20s
                                              ω = 0,314 rad/s
                                               v = ωR
                                               v = 0,314 rad/s * 840 m
                                               v = 263,89 m/s
                                               ac = v²/R
                                               ac = (263)²/840m
                                                ac = 82,90 m/s²
