This looks good. (How do f and F relate?)kranav said:fnet = f - umg = ma1 1st case
Fnet = F - umg = ma2 2nd case
Try it one more time.The Attempt at a Solution
I tried to solve it but u comes out to be zero.

The coefficient of friction is a measure of the amount of resistance between two surfaces in contact when one is moving relative to the other. It is a dimensionless quantity, meaning it has no units.
The coefficient of friction is calculated by dividing the force required to move one surface over another by the force pressing the two surfaces together. This can be expressed as μ = F/N, where μ is the coefficient of friction, F is the force required to move the surfaces, and N is the normal force between the surfaces.
The coefficient of friction can be affected by several factors, including the nature of the surfaces in contact, the roughness of the surfaces, the force pressing the surfaces together, and the presence of any lubricants or contaminants.
A low coefficient of friction means that there is less resistance between two surfaces in contact, making it easier for one surface to slide over the other. This can be beneficial in reducing wear and tear on surfaces and decreasing the force required for movement.
The coefficient of friction is important in many areas of science and engineering, as it affects the performance and efficiency of machines and structures. It is also relevant in everyday life, as it helps us understand why objects move or slide against each other and how to improve their movement.
