18:-A 25.0-kg block is released from rest at point A in the following Fig IHe ValXII frictionless except for the portion between points B and C, which has a length of 6.00 m. The block travels down the track, hits a spring of force constant 2250 N/m, and compresses the spring 0.300 m fro its equilibrium position before coming to rest momentarily. Determine the coef ficient of kinetic friction between the block and the rough surface between points B and...

1. I have a six sided die. My suspicion is that the die is not fair, rather it is weighted to rol twos more often then expected with a fair die. To investigate this I roll the die 100 times. In those 100 rolls, I observe 21 twos.
