A block of mass m slides on a circular track of radius r whose wall and floor both have coefficient of kinetic friction u with the block The size of block is small compared to the radius of the track The floor lies in horizontal plane and the wall is vertical The block is in contact with both wall and the floor The block has initial speed vo along tangent of circular track For the block to circle the track exactly once before coming to rest initial velocity vo needed is A B C D rg e rg 4 x rg 2 LUXE rg 2 m 041
