3. A rocket is flying horizontally in the sky. At time instant $t$, the mass of the rocket is $M$; the velocity of the rocket is $U$ relative to the ground; the exhaust gas is coming out of rocket nozzle at a speed of $Vo$ and mass flow rate is $\dot{m}$. Assuming the air resistance force on the rocket is a constant value of $D$ and the rocket is accelerating at $a$. Please derive the expression of $a$. (Please choose C.V. properly and explain why) $U, a$ $Ao, Vo, \dot{m}, P1$ (gage pressure) $D$

piece of roof ballast (stone) that falls (effectively, is released from rest) from the top of a building travels 12.8 m in the last second before it hits the ground. How high is the building? By the way, describing a projectile as stone (vs hollow plastic, for example) is one way to imply that air resistance is likely to be negligible in comparison to gravity.

Your instructor often uses the generic pronoun "he" when referring to psychologists, and the generic pronoun "she" when referring to administrative assistants and other clerical staff. In your mind, you find you are automatically thinking of psychologists as men and administrative assistants as women. Why? You are thinking in images too much. The linguistic determinism hypothesis predicts that language will shape your thinking. "She" and "her" are truly gender free, but "he" and "his" are not. The linguistic determinism hypothesis predicts that your thinking will shape your language.

(a) \lim_{x \to -6} (7x + 43) = 1 (b) \lim_{x \to 3} x^3 = 27 (it may be useful for (b) to remember the identity ($a^3 - b^3$) = ($a - b$)($a^2 + ab + b^2$))

Guess the value of the limit (if it exists) by evaluating the function at the given numbers. (It is suggested that you report answers accurate to at least six decimal places.) Let $f(x) = \frac{e^{2.6x} - e^{4.8x}}{x}$. We want to find the limit $\lim_{x \to 0} f(x) = \lim_{x \to 0} \frac{e^{2.6x} - e^{4.8x}}{x}$. Start by calculating the values of the function for the inputs listed in this table. $x$ $f(x)$ 0.2 0.1 0.05 0.01 0.001 0.0001 0.00001 Based on the values in this table, it appears $\lim_{x \to 0} \frac{e^{2.6x} - e^{4.8x}}{x} = $

Name: PART II: USE THE COMPUTER Problem5t (40points) In a lottery game, the player is asked to enter 5 positive integers. The winning prize depends on the ratio of the highest number (Max) to the lowest numbers (Min) entered by the player. • If the remainder of the ratio (Max/Min) is odd, the winning prize is 2,000 dollars. • If the remainder of the ratio (Max/Min) is even, the winning prize is 1,000 dollars. • In all other cases, the winning prize is 500 dollars. 1) Please write a C++ program to design the game and answer the question below after entering the following numbers: 1 7 3 78 67. a) The minimum value (10 points) b) The maximum value (10 points) c) The remainder of the ratio (Max/Min) (5 points) 2) Test your program with 5 different integers of your choice. (10 points) 3) Make your program calculate the value of variable $c = \sqrt{Max^2 + Min^2}$ with the integers that you entered in question 3); and display your answer with 5 significant digits. (5 points). Please email your program to mkoffi@hostos.cuny.edu
