B. The soccer ball and the car experience the same acceleration due to gravity.E. The soccer ball and the car experience the same gravitational force.

Explicación

## Step 1The problem involves understanding the principles of gravity and acceleration. According to Newton's second law of motion, the force of gravity on an object is directly proportional to its mass. This means that the heavier the object, the greater the force of gravity it experiences. However, the acceleration due to gravity is constant for all objects, regardless of their mass. This is known as the principle of equivalence, which states that all objects fall at the same rate in a vacuum.## Step 2In this problem, both the soccer ball and the car are dropped from the same height in a vacuum on Earth. This means that the acceleration due to gravity is the same for both objects, which is approximately 9.8 m/s².## Step 3The time it takes for an object to fall to the ground is determined by the equation , where is the time, is the height, and is the acceleration due to gravity. Since the height and the acceleration due to gravity are the same for both objects, the time it takes for them to fall to the ground is also the same.## Step 4The gravitational force experienced by each object is dependent on its mass. The heavier the object, the greater the gravitational force it experiences. Therefore, the car, being heavier than the soccer ball, experiences a greater gravitational force.
