Question

un corredor pedestre corre 200 metros en 21,6 segundos.calcular su velocidad m/s,km/h y m/mi

Answer 1

  Los datos son:
  d = 200 m
  t = 21,6 s
  v = ?
                De la Cinemática del MRU conocemos:
                                                  v = d/t
                                                  v = 200m/21,6s
                                                  v = 9,26 m/s
             9,26 m/s (1Km/1000m)(3600s/1h) = 33,34 Km/h
             9,26 m/s (60s/1min) = 555,6 m/min
