the mass of the cart increased to 2 kg
To calculate the new mass of the cart, if the mass increased to 2 kg, simply add the increase in mass to the previous mass.
To calculate the new mass of the cart, you need to know the original mass of the cart and the amount by which it has increased. Let's assume that the original mass of the cart was 1 kg and it increased by 1 kg.
To find the new mass, you simply add the increase to the original mass:
New mass = Original mass + Increase in mass
New mass = 1 kg + 1 kg
New mass = 2 kg
Therefore, the new mass of the cart is 2 kg.
