							We know that ,Acceleration = change in speed per unit timeInitial Speed = 10 m/secFinal Speed = 40 m/secChange in speed= (40-10)m/sec = 30m/secTime taken to accelerate = 15 secsSo, acceleration = change in speed / time                              =30 m/sec / 15 sec                              =30/15 m/sec2                              =2 m / sec2
