A girl is pushing a box towards east direction. In which direction should her friend push the box so that it moves faster in the same direction?

Options

A. West
B. East
C. North
D. South

Answer

To solve the problem of determining the direction in which the girl's friend should push the box to make it move faster in the same direction, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Initial Direction of Force**:
- The girl is pushing the box towards the east. This means there is a force acting on the box in the east direction.

2. **Understanding the Concept of Force Addition**:
- When multiple forces act on an object, the total or net force is the vector sum of all the individual forces. If two forces act in the same direction, they add up to increase the net force.

3. **Determine the Direction for the Friend's Push**:
- To make the box move faster in the east direction, the friend should also apply a force in the same direction (east). This will result in a greater net force acting on the box.

4. **Conclusion**:
- Therefore, the friend should push the box towards the east as well. This will increase the speed of the box since both forces (the girl’s and her friend’s) will be contributing to the motion in the same direction.

### Final Answer:
The friend should push the box towards the **east**.
