Question

A smooth block is released at rest on a 45° incline and then
slides a distance ‘d’. The time taken to slide is ‘n’ times as
much to slide on rough incline than on a smooth incline.
The coefficient of friction is
(a) μₖ = √1-1/n²(b) μₖ = 1- 1/n²
(c) μₛ = √1- 1/n² (d) μₛ =1- 1/n²

Answer 1

Answer:

UK 11.3 a small block is released at least on a 45 degree so incline of themselves are the strengths day the time taken to slide is the two times must be brought to the smooth incline so the answer would be sorry I don't know the answer if I would know I will tell you 6 class ok how it helps and I think you should be many likes because I have not tell you wrong answer I have must tell that I don't know I have tell right to if we don't know we should not be like this it would hurt somebody that how is giving the answer what is the explanation of answer so we should not answer just simply it would be of my class of 6th class I will tell it and I use my mums in in for doing this thanks
