A 5 kg blue block is released from rest at point A (3m high) and slides down a track. The track consists of a curved ramp and a horizontal surface seamlessly connected. The whole track is frictionless except for the portion between point B and C, which has a length of 6m. The coefficient of kinetic friction is µk = 0.35. (a) Please find out the velocity of the blue block when it arrives at the bottom of the ramp. . (b) Please find out whether the block can pass through the rough region BC. If you believe it can pass through, please find out its speed when it arrives at point C. If you believe it cannot pass through and stop somewhere on the track, please identify its final position with the distance to point B.. (c) Determine how much heat is generated at the rough surface due to friction
