A toy car released with the same initial speed will travel farthest on

Options

A. muddy surface
B. cemented surface
C. polished marble surface
D. brick surface

Answer

To determine the surface on which a toy car, released with the same initial speed, will travel the farthest, we need to consider the effect of friction on the motion of the car.

### Step-by-Step Solution:

1. **Understanding Friction**: Friction is a force that opposes the motion of an object. The amount of friction depends on the nature of the surfaces in contact. Different surfaces have different coefficients of friction.

2. **Types of Surfaces**: Common surfaces include rough surfaces (like carpet or sandpaper) and smooth surfaces (like polished marble or glass). Rough surfaces have a higher coefficient of friction, leading to more resistance against the motion of the toy car.

3. **Effect of Initial Speed**: When the toy car is released with the same initial speed on different surfaces, the frictional force acting on the car will vary based on the surface type.

4. **Identifying the Best Surface**: To maximize the distance traveled by the toy car, we need to minimize the frictional force acting on it. The surface with the least friction will allow the car to maintain its speed for a longer distance.

5. **Conclusion**: Among the surfaces considered, a polished marble surface has the least friction. Therefore, the toy car will travel farthest on a polished marble surface when released with the same initial speed.

### Final Answer:
A toy car released with the same initial speed will travel farthest on a polished marble surface.
