Q1. A U tube is filled with water, and the two arms are capped. The tube is cylindrical, and the right arm has twice the radius of the left arm. The caps have negligible mass, are watertight, and can freely slide up and down tube.
If a 1 mass block is on the left cap, how much total mass must be placed on the right cap so that the caps equilibrate at equivalent height?
Q2. What is the terminal speed for an 82.00 skier going down a 43.00 snow-covered slope on wooden skis = 0.06?
