If you double the amount of mass in a shopping cart by adding food to it, what do you have to do to the force to maintain the same acceleration as you had before?

Reduce the force

Explanation:

By newtons third law

F=m×a

or

Force =Mass ×Acceleration

In other words

Acceleration=Force/Mass

If the mass drops, to maintain the same acceleration, you need to reduce the force too
