A bus starts from rest and attains 40km/hr velocity after 10sec . Calculate the acceleration of bus in m/sec2

  1. Nonetheless

    First convert 40 km/hr to m/hr:
    40 km/hr x 1000 m/km
    = 40 000 m/hr
    Now convert 40 000 m/hr to m/s:
    40 000 m/hr / 3600 s/hr
    ~ 11.11 m/s

    acceleration = change in velocity / change in time

    = (11.11 m/s - 0 m/s) / 10 s
    = ?
