A rescue helocopter , moving with a constant horizontal speed at a certain height above the ground , drops a food packet from it . If air resistance is negligible, the food packet will land (a) below the plane and ahead of it (b) below the plane and behind it or (c) directly below the plane .

Explanation

To solve the problem, we need to analyze the motion of the food packet dropped from the helicopter. Here’s a step-by-step breakdown:

### Step 1: Understand the Initial Conditions
- The helicopter is moving horizontally with a constant speed \( U \) at a certain height above the ground.
- When the food packet is dropped, it has the same horizontal speed \( U \) as the helicopter.

**Hint:** Remember that objects in free fall maintain their horizontal velocity when dropped.
