Chapter 7.2, Problem 51E
Air resistance (adapted from Putnam Exam, 1939) An object moves in a straight line, acted on by air resistance, which is proportional to its velocity; this means its acceleration is a(t) = −kv(t). The velocity of the object decreases from 1000 ft/s to 900 ft/s over a distance of 1200 ft. Approximate the time required for this deceleration to occur. (Exercise 38 may be useful.)

Problem D: Different Dice Game
Consider the following game for two players:
The first player rolls a pair of dice of fair six-sided dice. If the two dice show different numbers,
the player's score is the larger of the two numbers. Otherwise, the player's score is the sum of the
two numbers.
At this point, the player is asked if they want to remove their lower die and re-roll one die. If
they say no, the player keeps her score and their turn is over. If they say yes, then they roll one
more die and the number showing on this die replaces the lower of the original two rolls. Then
these two dice rolls are scored accordingly. (For example, if the initial roll was a 2 and 5, if the
player doesn't roll again, she gets 5 points. If she does roll again and obtains a 4, her score is still
5. If she rolled again and obtained a 6, her score would be a 6. If she rollwed again and obtained
a 5, her score would be a 10.)
The second player goes after the first, doing the exact same steps as the first…
Part 4: For circle, square and annulus write a program to find the area, perimeter (or circumference) for a range of parametric values given by the user and plot the corresponding shapes in the range given. User needs to identify lower and upper values of each parameter. The identified range for the parameters should be then divided into 10 monotonic steps inside your program. Accordingly, you need to calculate the values and plot the shapes corresponding to all 10 values in the range identified by the user. The program should plot the geometries in the first quadrant.
Interest Rates Savings accounts state an interest rate and a compounding period. If theamount deposited is P, the stated interest rate is r, and interest is compounded m timesper year, then the balance in the account after one year is P⋅(1+rm)m. For instance, if$1000 is deposited at 3% interest compounded quarterly (that is, 4 times per year), thenthe balance after one year is1000⋅(1+.034)4=1000⋅1.00754=$1,030.34.Interest rates with different compounding periods cannot be compared directly.The concept of APY (annual percentage yield) must be used to make the comparison. TheAPY for a stated interest rate r compounded m times per year is defined byAPY=(1+rm)m−1.(The APY is the simple interest rate that yields the same amount of interest after oneyear as the compounded annual rate of interest.) Write a program to compare interestrates offered by two different banks and determine the most favorable interest rate. SeeFig. 4.24.

- The number of lines that can be printed on a paper depends on the paper size, the point size of each character in a line, whether lines are double-spaced or single-spaced, the top and bottom margin, and the left and right margins of the paper. Assume that all characters are of the same point size, and all lines are either single-spaced or double-spaced. Note that 1 inch = 72 points.Moreover, assume that the lines are printed along the width of the paper. For example, if the length of the paper is 11 inches and width is 8.5 inches, then the maximum length of a line is 8.5 inches.

- Phyton The surface of the Earth is curved, and the distance between degrees of longitude varies with latitude. As a result, finding the distance between two points on the surface of the Earth is more complicated than simply using the Pythagorean theorem. Let (t1, g1) and (t2, g2) be the latitude and longitude of two points on the Earth’s surface. The distance between these points, following the surface of the Earth, in kilometers is: distance = 6371.01 × arccos(sin(t1) × sin(t2) + cos(t1) × cos(t2) × cos(g1 − g2)) The value 6371.01 in the previous equation wasn’t selected at random. It is the average radius of the Earth in kilometers. Create a program that allows the user to enter the latitude and longitude of two points on the Earth in degrees. Your program should display the distance between the points, following the surface of the earth, in kilometers. Hint: Python’s trigonometric functions operate in radians.

Nobody really wants to be the one to take the news; the way goes through enemy territory and, even if the messenger gets through, the classic fate of the bearer of bad news may be waiting. (Let's just say, this is how the phrase "Don't shoot the messenger" became relevant.) To determine which messenger will be sent, X sits all of his messengers down in a circle, selects a number, and starts to count off. Messengers are allowed to leave the circle one by one, and the last messenger left is the one who will deliver the bad news. The counting off procedure is slightly unusual, however, because it is actually the messenger after the last one counted who gets to leave the circle. Consider the following example with 5 messengers, in which the number selected for counting off is 7. We'll start at the "head" of the list and move forward. Since it is circular, the "head"…arrow_forwardCorrect answer will be upvoted else downvoted. Computer science.
