# You are pushing a heavy box across a rough floor. When you are initially pushing the box, and it accelerates,(a) you exert a force on the box, but the box does not exert a force on you.(b) the box is so heavy that it exerts a force on you, but you do not exert a force on the box.(c) the force you exert on the box is greater than the force of the box exerting back on you.(d) the force you exert on the box is equal to the force of the box exerting back on you.(e) the force that the box exerts on you is greater than the force you exert on the box.

The correct option is (d).

See the step by step solution

## Step 1. Force between you and the box

According to the third law of motion, the force you exert on the box is equal to the force exerted on you by the box.

## Step 2. Other forces on the box

However, there are other forces, such as friction acting on the box. The box accelerates because there is a net force on the box due to all the force on it.
