Solve Kinematic Problem with Friction Along Curve | Mass Included

[mrh584]

Please see the attached problem I came up with. I've done similar problems to this in school, but never with the frictional force acting along a curve. I'm wondering if my solution is valid, or if the integral needs some work?

And I just realized I left out the mass [M] in the normal force equation, and all other equations that use it.

Your solution is wright. Find the integral and substitute the limits,and get the result..

I would first like to commend you for taking on a challenging problem and seeking feedback on your solution. Solving kinematic problems with friction along a curve can be tricky, and it is important to make sure all variables and equations are accounted for.

Upon reviewing your solution, I have noticed that you did indeed leave out the mass [M] in the normal force equation and other equations that use it. This is a crucial variable that cannot be omitted as it affects the magnitude of the normal force and ultimately, the frictional force.

To ensure the validity of your solution, I would recommend going back and including the mass [M] in all relevant equations. This will provide a more accurate and complete solution to the problem. Additionally, it may be helpful to double-check your integral to ensure all variables and constants are properly accounted for.

In conclusion, your approach to the problem is valid, but it is important to include all relevant variables and equations in order to obtain an accurate solution. Keep up the good work in tackling challenging problems and seeking feedback to improve your skills as a scientist.
