Our textbook for this summer assignment will be OpenStax College Physics for AP Courses. Please read/study sections 11.3, 13.1, 13.3, and 13.4 in the book, and then do Problems 11 and 13 in the "Problems and Exercises" section for Chapter 11, and some of the questions in the Test Prep for AP Courses for Chapter 13. Put your answers below. If you format your answers correctly, formative will auto-grade when you submit the assignment. Include units on all answers, with a space before the unit. For instance, "27.4 km/s". Express large and small numbers in scientific notation with the letter e: "4.5e13 kg".
After this there are a few TIPERs problems to look at from our TIPERs workbook. You should be receiving this in the mail before the school year starts. If you do not receive it by then, do not fret, you will still be prepared to start AP Physics 2 on our first day with the rest of the parts in the summer assignment. I will offer an extension of the TIPERs questions due date if you book is delayed.

Question 1
1.
11.
As a woman walks, her entire weight is momentarily placed on one heel of her high-heeled shoes. Calculate the pressure exerted on the floor by the heel if it has an area of 1.50 (cm*cm) and the woman’s mass is 55.0 kg. Express the pressure in Pa. (In the early days of commercial flight, women were not allowed to wear high-heeled shoes because aircraft floors were too thin to withstand such large pressures.)

Question 2

13.
Nail tips exert tremendous pressures when they are hit by hammers because they exert a large force over a small area. What force must be exerted on a nail with a circular tip of 1.00 mm diameter to create a pressure of 3.00×10^9 N/(m*m)?(This high pressure is possible because the hammer striking the nail is brought to rest in such a short distance.)

Question 4
4.
Two samples of ideal gas in separate containers have the same number of molecules and the same temperature, but the molecular mass of gas X is greater than that of gas Y. Which of the following correctly compares the average speed of the molecules of the gases and the average force the gases exert on their respective containers?
