Answer:
b) Which surface is the smoothest?
Explanation:
If Sujata was to push a trolley using similar force on three different surfaces and measured the distance, she would be able to identify which surface is the smoothest.
- Force is a product of mass and acceleration.
- In the above-mentioned case, the mass remains the sane in all three situations. That is, the same trolley is used.
- But the distance moved by it is different in all three cases irrespective of providing the same force.
- This is because of the varying friction that is provided by the three surfaces.
- The trolley will move the most distance on a surface with less friction (more smooth) and it will move the least on surfaces which provides high friction.
