A block of mass 2 kg begins with velocity 2.3 m/s at the top of a curved track at a height h= 9.9 m and travels around a circular loop of radius R. There is negligible friction between the block and the track between points A and D, but the coefficient of kinetic friction on the horizontal surface between points D and E is u=0.4. If the block stops at point E, what is the distance (in m) between points D and E? A 2R
