A pushing force acts on a toy car for 3 seconds causing it to accelerate at a rate of 10 m/s. If the car is replaced with a similar, but larger toy of 2 times greater mass and the same pushing force is applied for the same amount of time, the acceleration of the larger toy car will be ______.
5 m/s (or half the rate of the first car)
