Question #1: No response Imagine that you are on Mars and you need to launch a SpaceX Starship rocket back to Earth. Use the information provided below to calculate the acceleration and speed of the rocket, and remember that the gravitational acceleration on Mars is lower than it is on Earth (provided below). You can neglect air resistance in your calculation. $g_{Mars}$ = 3.72 m/s$^2$. Initial mass of the rocket = 3700000 kg. Mass flow = 21800 kg/s. Exhaust gas velocity = 4050 m/s. Time for speed check in part (b): 64 s A) Calculate the initial acceleration of the rocket: (1.5 marks) m/s$^2$. B) Calculate the speed of the rocket after the time given above: (0.8 marks) m/s.

Suppose the angle A satisfies $0 < A < 2\pi$. If $\cos(A) = 0.81$ and $\sin(A) > 0$, determine: The quadrant for the angle $A/2 = \boxed{1}$ Then, Be certain to express all answers to at least four decimal places. Also, be careful regarding the signs for each of your answers. $\sin(A) = 0.5857$ $\sin(A/2) = \boxed{}$ $\cos(A/2) = \boxed{}$ $\tan(A/2) = \boxed{}$

Suppose Rosa earns $850 per week working as a driving instructor for Passing Left. She uses $8 to take a spin class at Silver’s Gym. Silver’s Gym pays Nick $475 per week to work as a trainer. Nick uses $125 to purchase driving lessons from Passing Left. Identify whether each of the following events in this scenario occurs in the factor market or the product market. Event Factor Market Product Market Rosa spends $8 to take a spin class. Rosa earns $850 per week working for Passing Left. Nick earns $475 per week working for Silver’s Gym. Which of the elements of this scenario represent a flow from a firm to a household? This could be a flow of dollars, inputs, or outputs. Check all that apply. The spin class Rosa receives Rosa's labor The $125 Nick spends to purchase driving lessons from Passing Left The $475 per week Nick earns working for Silver’s Gym

3) Draw the shear and bending moment diagrams for the beam and loading shown to the right. Determine: a) the maximum magnitude of the shear and of the bending moment, and b) the maximum normal stress due to bending. (Hint: you must find centroid of the trapezoid, and calculate $I$. Ans: $\bar{y} = 1.33$ in, $I_z = 4.063$ in$^4$) Ans. $|V_{max}| = 9280$ lb, $|M_{max}| = 28,224$ in-lb, $\sigma_{max} = 11.53$ ksi

Hard-code the following 10 values into array a: 128, 10, 23, 12, 128, 9, 220, 46, 128, 5 • Hard-code n = 10 • Prompt the user to enter a value as follows: "Please enter an integer value" • Read the integer value and store it (let's call it x) • Call the function count with the following arguments: count(a, 10, x) • Output the results as follows: "The number of times x appears in the list is res times" • Exit the program Implement the function count in assembly to use it in this part. The equivalent function count (in C) is defined as follows: int count(int a[], int n, int x) { int res = 0; int i = 0; for (i = 0; i != n; i++) if (a[i] == x) res = res + 1; return res; }
