Options

A. may be on an elliptical path
B. is moving on a straight path without acceleration
C. is moving on a straight path with acceleration
D. is moving without any acceleration

Explanation

To solve the problem, we need to analyze the situation described in the question. Here's the step-by-step solution:

### Step 1: Understand the terms
The question states that a car is moving with a uniform speed, meaning the speed (magnitude of velocity) remains constant. However, it also mentions that the momentum of the car is changing.

**Hint:** Remember that momentum is defined as the product of mass and velocity (p = mv).

### Step 2: Analyze momentum
The formula for momentum is given by:
\[ p = m \cdot v \]
Where:
- \( p \) is momentum,
- \( m \) is mass,
- \( v \) is velocity.

Since the mass of the car is constant, if the momentum is changing, it implies that the velocity must be changing.

**Hint:** Consider what aspects of velocity can change: magnitude (speed) and direction.

### Step 3: Determine the nature of velocity change
Since the speed is uniform (constant), the change in momentum must be due to a change in the direction of the velocity. This indicates that the car is not moving in a straight line but is instead changing direction.

**Hint:** Think about motion in curves or circular paths where direction changes.

### Step 4: Identify the path of motion
The car could be moving in a circular path or an elliptical path. In both cases, the direction of the velocity vector changes continuously, which results in a change in momentum.

**Hint:** Recall the characteristics of different paths: straight paths have constant direction, while circular and elliptical paths have changing directions.

### Step 5: Conclusion
Since the question provides options and we have established that the car is changing direction while maintaining constant speed, the most appropriate conclusion is that the car is moving along an elliptical path (or possibly circular, but the question specifies elliptical). Therefore, the correct option is that the car is moving on an elliptical path.

**Final Answer:** The car is moving on an elliptical path.
