Tо receive credit fоr yоur аnswers you must show аll work, including diаgrams, and the appropriate units at each step. 1. (6 pts) A person carries a board that is 8m long with one hand pushing down on it at the right end with a force F1 and the other hand holding it up 51 cm from the right end of the board with force F2. The board has a mass of 10 kg and its center of gravity is at the middle of the board. a. (1.5 pts) Draw an FBD for the board, showing all forces, distances, and indicate a positive direction for torque as well as positive x and y directions. Indicate the right end of the board as the axis of rotation. b. (1.5 pts) With the right end of the board as the axis of rotation, write the summation of torque equation, with all of the torques on the left and zero on the right side. Fill in all known values and fill in logical variable names for unknowns. You do not need to solve it. c. (0.5 pts) Write the second law equation for the vertical direction, just as above, filling in known values and unknowns and putting zero on the right side of the equation. You do not need to solve it. d. (1.5 pts) Now, with the axis of rotation at the left end of the board, write the summation of torque equation, like you did in part b. You do not need to draw a new FBD. You do not need to solve it. e. (0.5 pts) Would it be possible to solve for the 2 unknown forces if you only used the equation in b? f. (0.5 pts) Instead of using equation in b, would it be possible to solve for the 2 unknown forces if you only used the equations in c and d?

Write а prоgrаm thаt calculates hоw much mоney a user's laundry mat makes a month on average. Specifically, you should: Ask the user to input the number of quarters collected from the laundry mat each month for 6 months. See the example interaction below. Calculate the average number of quarters collected from the laundry mat in a month (sum divided by number of months). Round the average to the nearest whole number. Convert the average number of quarters collected to dollars and cents (e.g. 70 quarters would equal $17.50) Output the amount of money the laundry mat makes per month on average in dollars and cents. The total should be rounded to exactly 2 decimal places. The output should be labeled and easy to understand. Not including comments, a solution will be approximately 10-15 lines long. An example interaction is below. Remember that the black text is just sample user input. The blue text was created by the python program. This is just an example interaction. Your program should work regardless of what numbers are input. IMPORTANT: To submit your program.... In a new tab, navigate to the Midterm Part 2 SUBMISSION ONLY Assignment. Honorlock will likely not let you navigate away from this page on this tab, so you will have to open Canvas and navigate to the submission only assignment in a new tab. Follow the instructions there for submitting your programs. You should NOT submit this part of the midterm until you have submitted ALL 3 of your files to the Midterm SUBMISSION ONLY assignment
