Un ciclista con movimiento uniformemente acelerado inicia un recorrido en línea recta de 50 m con rapidez de 3,0 m/s. Si el recorrido lo hace en 8,0 s ¿que rapidez alcanza al final de ese trayecto?

50.)the diagram below represents the wave fronts produced by a point source moving to the right in a uniformmedium. observers are located at points a and b.compared to the wave frequency and wavelength observed at point a, the wave observed at point b has a(1) higher frequency and a shorter wavelength(2) higher frequency and a longer wavelength(3) lower frequency and a shorter wavelength(4) lower frequency and a longer wavelength
