Question A vehicle platoon was observed over a distance of 600 meters on a single lane of Epping Road, entering at Point A and departing at Point B. Considering the first 30 seconds at \( A \) as the period of observation, calculate spot speed of individual vehicles time mean speed space mean speed by using harmonic mean average volume density for these ten observed A vehicle platoon was observed over a distance of 600 meters on a single lane of Epping Road, entering at Point A and departing at Point B.

1050. A bullet weighing 1 lb is fired vertically upward with a muzzle velocity of 3000 ft per sec. If the velocity is 2950 ft per sec after 1 sec, what is the average air resistance on the bullet? What maximum height will the bullet reach, assuming that the air resistance remains constant? Ans. R = 0.55 lb; Max h = 90,000 ft 1 1051. Two blocks A and Roro rolonged f non

You can and should start with the examples from the textbook/presentation and adapt them to the assignment at hand and use the appropriate names and add the additional code and requirements bellow. Design a program/project/driver class Your Name Assignment and the following classes (with exact names, replace Your Name with your actual first name or the name you go by): Class Description YourNameList Program the complete version of user-defined MyList class from Chapter 24 (meaning you need to add the code for all methods that were not coded in the textbook/presentation and have a "left as an exercise" comment). Add an additional YourNameToString method that returns a string with the elements from the list in the format: (Elementpositiono, ElementPostioni, ....

4. Consider the determinant as a sum of signed products. Recall that there are \( n \) ! elementary products in the determinant expansion of an arbitrary \( n \times n \) matrix \( A \). (a) If \( A \) is a \( 5 \times 5 \) matrix, how many of the elementary products in \( \operatorname{det}(A) \) are guaranteed to be zero if the entry \( a_{12} \) is zero? (b) If \( A \) is an \( n \times n \) matrix, \( n \geq 2 \), how many of the elementary products in \( \operatorname{det}(A) \) are guaranteed to be zero if \( a_{12}=0 \) ? Give your answer in terms of \( n \). (c) If \( A \) is an \( n \times n \) matrix with \( \operatorname{det}(A) \neq 0 \), what is the maximum possible number of zero entries in A? Give your answer in terms of \( n \).

Drop down choices for both a. and b. -cost-push inflation -a change in inflation expectations -demand-pull inflation The Phillips Curve and Inflation - End of Chapter Problem For each scenario, determine whether inflation expectations, demand-pull inflation, or cost-push inflation will change. a. A rapid influx of foreign investment causes the output gap to become more positive. This gives rise to b. The president unexpectedly announces a tariff on aluminum and steel. This causes

CIRCLE ALL ANSWERS AND PROVIDE UNITS 1. (20 points) Mohr's Circle and Stress Elements Oy An element in plane stress (shown above) is subjected to stresses Ox - 70 MPa, Oy, and Txy - 50 MPa. Using the Mohr's Circle equations, determine the following: a principal stresses, b. the maximum shear stress, C. the principal angle, d. If one of the principal stresses is negative, what does a negative stress mean? **Using just proper equations is acceptable, but Extra Credit will be given if Mohr's Circle is drawn out.

You make a swimming pool 3.92 M in magnesium acetate, Mg(CH3COO)2 hoping to keep it from freezing during the winter. Its density is 1.23 g/ml. What will its normal freezing point be? Give your final answer (remember, you're looking for the new normal freezing point) to 1 decimal place (just to keep CuLearn happy) Put C for your unit (I don't know how to find the degree sign for answers...) Kf(H2O) = 1.86 °C/m
