QUESTIONS 1. Did the kinetic or static frictional coefficient vary with normal force? Give your conclusions and support them based on your simulation results from Parts A and B. 2. Which is bigger theoretically, the static or the kinetic frictional coefficient, and why? 3. Two masses mi and my are connected using a string as shown in figure 3 above. m1 is the mass of the sliding block and my is the hanging mass and is 2.0 Kg. The coefficient of static friction between mass and the table is 0.40, whereas the coefficient of kinetic friction is 0.30 (a) What minimum value of mi will keep the system from starting to move? (b) What value(s) of mi will keep the system moving at constant speed? Show all your work including formulas with numbers plugged-in
