Question

Two masses m1 and m2 where m1 is greater than m2 slide down a rough inclined surface of the same length and inclination.Which of the masses would be the first to get to the bottom? Give reasons for your answer

Answer 1

Answer:

m2 mass would be first to get the bottom

Explanation:

Because friction force depends on volume

Answer 2

Answer:

Both of the bodies with two different masses will reach the bottom at the same time.

Explanation:

• The resistance provided by the surface to the object which is moving across that surface, is called friction.
• Friction is a product of normal force and frictional coefficient.
• On plane surface normal force is the product of gravity and mass so frictional force is directly proportional to the mass of the object.
• In an inclined plane frictional force acts like gravity and inertia.
• Thus, the mass of the body does not affect the speed of the object sliding through the inclined plane.

So, even if the two bodies have two different masses, one greater than the other, it will still not affect which body reaches the bottom first.
