B. Both the earth's gravity on the ball and the force the ball got from being rolled off the table.
Explicación
## Step 1The problem involves understanding the forces acting on a ball that is rolled off a table. The forces in question are the force that the ball gets from being rolled off the table and the force of the earth's gravity on the ball.## Step 2The force that the ball gets from being rolled off the table is an initial force that sets the ball in motion. This force is applied when the ball is rolled off the table.## Step 3The force of the earth's gravity on the ball is a constant force that acts on the ball throughout its motion. This force is always present and acts downwards, towards the center of the Earth.## Step 4When the ball leaves the table, it is still under the influence of the force of the earth's gravity. This force will continue to act on the ball until it hits the floor.## Step 5Therefore, both the force that the ball gets from being rolled off the table and the force of the earth's gravity on the ball act on the ball after it leaves the table but before it hits the floor.
