1. Explain why, is it easier to drag a mat on floor when nobody is sitting on it but much more difficult to drag the same mat when a person is sitting on it. 2. When a pencil cell is released from a certain point on an inclined wooden board, it travels a distance of 35 cm on floor A, before it comes to rest. When the same pencil cell is released from the same point on the same inclined board it travels a distance of 20 cm on floor B before coming to rest which floor, A or B offers grater friction? Give reason for your answer. please answer this i will mark you brainlist and follow you

The friction between the mat and the ground increases in the second case which reduces the net force applied on it. This is because frictional force is directly proportional to the 'weight' of the body that moves with respect to a surface. So in the second case, the weight of the body (mat+Person) is higher and would have more friction that would oppose the motion.

Answer:

1. in this case gravitational force play a major role.

weight = mass× acc due to gravity.

as mass of an object increase, the attraction btwn floor n object will also increase.

when compared to only mat, mat with a person on it will be difficult to pull... as already strong vertical pull take place, and that makes a horizontal pull impossible

2. I don't know yarr... sorry
