# Friction in vertical circular motion

Consider the above figure, the question is what should be the minimum velocity to be given to the block so that it just reaches the top most point of the loop. And yes friction does exist. Coefficient of friction between the block and the circular loop is $\mu$.

Can this problem be solved? If yes, please let me know.

I came up with this problem while solving a similar problem. I have no idea how to solve, u might

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

U can also solve it using only work energy theorem without polar coordinates, Solution.jpg
