Final answer:
According to Newton's 2nd Law, a shopping cart full of groceries will require more force to push due to its greater mass.
Step-by-step explanation:
According to Newton's 2nd Law, the force required to push an object is directly proportional to its mass and acceleration. The formula is given as F = ma, where F is the force, m is the mass, and a is the acceleration. In this case, the shopping cart full of groceries will require more force to push because it has a greater mass compared to an empty shopping cart. The mass of the groceries adds to the overall mass of the cart, increasing the force required to move it.
