2. Consider two masses conne two masses with friction". Assume that there is a significant friction between mass m, and the supporting, horizontal surface. What must be the value of the coefficient of kinetic friction u. for the two masses to move at a constant velocity? The constant velocity means that the acceleration a 0. Derive the formula for u, relative to masses m, and m. Remember that the condition for constant velocity is that the sum of forces acting...

Chapter 07, Problem 63 Two ice skaters have masses m, and m2 and are initially stationary. Their skates are identical. They push against one another, as in Figure 7.10, and move in opposite directions with different speeds. While they are pushing against each other, any kinetic frictional forces acting on their skates can be ignored. However, once the skaters separate, kinetic frictional forces eventually bring them to a halt. As they glide to a halt, the magnitudes of their accelerations...
