According to Newton's second law, F=ma. Since we know the force and acceleration in the first scenario, we can rearrange the equation to find the mass of the grocery cart: 
m = F/a = 10 N / 0.5 m/s^2 = 20 kg 
Now, if we apply a force of 20 N, the new acceleration can be found using the same equation: 
a = F/m = 20 N / 20 kg = 1 m/s^2 
Therefore, the correct answer is B, with an acceleration of 1 m/s^2.
