When a net horizontal force of 250 N acts on a 50-kg cart that is free to roll on a level surface, A) the cart accelerates at 9.8 m/s². B) the cart accelerates at 5 m/s². C) the cart accelerates at 12500 m/s². D) the cart accelerates at 0.20 m/s². E) the cart does not accelerate because it pushes back on the person with a force of 250 N.

The acceleration of the cart can be calculated using Newton's second law of motion, $F = ma$, where $F$ is the force applied, $m$ is the mass of the object, and $a$ is the acceleration. Substituting the given values, $250 \, \text{N} = 50 \, \text{kg} \cdot a$, solving for $a$ gives $a = \frac{250 \, \text{N}}{50 \, \text{kg}} = 5 \, \text{m/s}^2$.
