Section 5.5 Motion 521 Version: Fall 2007 5.5 Exercises In Exercises 1 - 12 , write down the for- mula d = vt and solve for the unknown quantity in the problem. Once that is completed, substitute the known quan- tities in the result and simplify. Make sure to check that your units cancel and provide the appropriate units for your so- lution. 1. If Martha maintains a constant speed of 30 miles per hour, how far will she travel in 5 hours? 2. If Jamal maintains a constant speed of 25 miles per hour, how far will he travel in 5 hours? 3. If Arturo maintains a constant speed of 30 miles per hour, how long will it take him to travel 120 miles? 4. If Mei maintains a constant speed of 25 miles per hour, how long will it take her to travel 150 miles? 5. If Allen maintains a constant speed and travels 250 miles in 5 hours, what is is his constant speed? 6. If Jane maintains a constant speed and travels 300 miles in 6 hours, what is is her constant speed? 7. If Jose maintains a constant speed of 15 feet per second, how far will he travel in 5 minutes? 8. If Tami maintains a constant speed of 1.5 feet per second, how far will she travel in 4 minutes? 9. If Carmen maintains a constant speed Copyrighted material. See: 1 of 80 meters per minute, how far will she travel in 600 seconds? 10. If Alphonso maintains a constant speed of 15 feet per second, how long will it take him to travel 1 mile? Note: 1 mile equals 5280 feet. 11. If Hoshi maintains a constant speed of 200 centimeters per second, how long will it take her to travel 20 meters? Note: 100 centimeters equals 1 meter. 12. If Maeko maintains a constant speed and travels 5 miles in 12 minutes, what is her speed in miles per hour? In Exercises 13 - 18 , a plot of speed v versus time t is presented. i. Make an accurate duplication of the plot on graph paper. Label and scale each axis. Mark the units on each axis. ii. Use the graph to determine the dis- tance traveled over the time period [0 , 5] , using the time units given on the graph. 13. t ( s ) v ( ft/s ) v 0 5 0 30 50

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
