A small block of mass 2 kg is projected on a horizontal smooth floor with speed 4 m s which merges into a rough vertical circular path in shape of a quarter circle as shown in the figure The coefficient of friction between the block and circular path is 0 2 If the radius of the circular path is 0 2 m then the speed of the block when it reaches end of circular path is the figure shows side view 1 2 m s 2 2 7 m s A
