1. The problem statement, all variables and given/known data A 25.0 kg block is released from point A (on a ramp, think of a skateboarders half pipe) at 3.00 meters. The track is frictionless except from points B to C (which has a length of 6m). The block travels down the track from point A to B, at which point it hits the friction section and travels to C. Question 1: Determine the coefficient of friction between the block and the rough patch between B and C Question 2: Determine the speed of the block at point C My attempts: I'm really struggling determining the coefficient of friction. When that is determined I don't think I'll have any issues finding the speed of the block.
