2.) The mechanical translation system shown in Figure 1 has an external force F applied to Mass 1 as an Input to the system. The Outputs of the system are the displacements of the two masses $X_1$ and $X_2$. Input: F Friction B2 Output: $X_1$ and $X_2$ $K_1$ B $K_2$ $M_1$ $M_2$ **See the Configuration guide in Appendix to configure the simulation parameters.** F $X_1$ $X_2$ Figure 1 a.) Create the block diagram representation for this mechanical system. Show all work in going from mechanical illustration to block diagram. b.) Once the block diagram is obtained, create this block diagram in Labview. c.) Run the simulation of this system in Labview: Plot the displacements of the masses $X_1$ and $X_2$ vs time. Use the following parameters in your simulation: Simulation Properties: Time step = 0.01 sec End time = 100 sec $M_1$ = 30 kg $M_2$ = 50 kg B = 150 N-s/m B2 = 3 N-s/m $K_1$ = 100 N/m, $K_2$ = 80 N/m, F = 20 N

1. [10 points] There is a CPU that spends 90% of its time executing a specific type of calculation when running an asteroid simulation. Its manufacturers make a change that improves its performance on that calculation 15 times. • 1. If the asteroid originally took 85 s to execute, what will the execution time now be after the changes have been introduced? • 2. What is the overall speedup? • 3. What fraction of its execution time does the new optimized system spend executing the calculation that was improved?
