A car driver collides with an airbag during a crash. The driver’s body, with a total mass of [m] kg, is moving at an initial speed of [v] m/s when it comes into contact with the airbag. The airbag brings the driver to rest over the time interval from 0 to t2. The figure shows the plot of the force magnitude exerted on the driver by the airbag as a function of time. t2 =[t2] × 10-2 s. Determine the maximum force Fmax in newtons (N).  

Box A, moving at an initial velocity of vA = [vA] m/s, collides with box B, which is initially at rest. The masses of the boxes are mA = [mA] kg and mB = [mB] kg. The collision is completely inelastic so the boxes stick together. Determine the kinetic energy of the system immediately after the collision (in joules).

Manuel like to spend his part of his monthly income on buying fitness membership and perfumes. Each fitness membership cost $25 per month, with marginal utility is 50.If his Marginal utility from buying perfumes is 160, how much it costs Manuel to buy each perfume?

If P < AVCAVC = average variable cost

Graph 1 In the graph above, which point is considered a high level of utility point?“high” level of utility.

If P > AVC but P < ATC, then the firm is:AVC = average variable costATC = average total cost

Consider the following multi-threaded pseudocode. Thread A: 1. lock (& mutex ); 2. if( queue . empty ()) { 3. cond_wait (&cv , & mutex ); 4. } 5. data = queue .pop (); 6. unlock (& mutex ); Thread B: 1. lock (& mutex ); 2. queue . insert ( data ); 3. cond_signal (& cv ); 4. unlock (& mutex ); Identify all bugs, if any exist. If you can define the bugfix then you will get extra credit A. Thread A Line 2 B. Thread A Line 3 C. Thread B Line 2 D. Thread B Line 3 E. No bugs    

Why does Shortest Job First (SJF) scheduling give us optimal time, but its implementation is not feasible in real life?
