Print "Censored" if userInput contains the word "darn", else print userInput. End with newline. Ex: If userInput is "That darn cat.", then output is: Censored Ex: If userInput is "Dang, that was scary!", then output is: Dang, that was scary! Note: If the submitted code has an out-of-range access, the system will stop running the code after a few seconds, and report "Program end never reached." The system doesn't print the test case that caused the reported message.

How far do you jog each morning? You prefer to jog in different locations each day and do not have a pedometer to measure your distance. Create an application to determine the distance jogged given the average number of strides ran during the fist minute, average number ran during the last minute, and the total minutes jogging. Design a modularized solution (with methods) to display the distance traveled. Pedometers measure the distance you run. However, you can also do a good estimate of the distance if you know your foot stride, how many strides you complete per minute, and the number of minutes you job. Foot stride is the distance covered by one average step length. Since everyone has a different foot size, strides differ. Manny people average 3 feet per setup when jogging. For this application, assume the foot stride is 2.5 feet. There are 5,280 feet in a mile. To establish how many strides per minutes, allow the user to input the number of strides made during the first minute jogging and the number of strides made string the last minutes of jogging. Use the average of those values to represent the strides per minute. Allow the user to input the total time spent jogging in hours and minutes. Write code that will display to distance traveled in miles.

A multilane highway (two lanes in each direction) is on level terrain. The free-flow speed has been measured at 45 mi/h. The peak-hour directional traffic flow is 1300 vehicles with 6% large trucks and buses and 2% recreational vehicles (f_p = 0.95).If the peak-hour factor is 0.85, determine the highway's level of service.

The natural water content of a Boston Blue Clay soil sample was found to be 14.6% through oven drying. It has been calculated that the maximum density for the clay will be obtained when the water content of the soil reaches 21.2%. Compute how many grams of water must be added to each 500 grams of Boston Blue Clay (in its natural state) in order to increase the water content to 21.2%.

A student team is to design a human-powered submarine for a design competition. The overall length of the prototype submarine is 4.85 m, and its student designers hope that it can travel fully submerged through water at 0.440 m/s. The water is freshwater (a lake) at T = 15 C. The design team builds a one-fifth scale model to test in their universitys wind tunnel. A shield surrounds the drag balance strut so that the aerodynamic drag of the strut itself does not influence the measured drag. The air in the wind tunnel is at 25C and at one standard atmosphere pressure. The students measure the aerodynamic drag on their model submarine in the wind tunnel. They are careful to run the wind tunnel at conditions that ensure similarity with the prototype submarine. Their measured drag force is 5.75 N. "Estimate the drag force" on the prototype submarine at the given conditions.
