There are several efficient ways to solve this problem. 1) Read your textbook thoroughly and try to understand the fundamentals. If textbooks are not available, google is a helpful resource.2) Your professor is not going to give you the solution but will surely help you in understanding the problem.3) Most workable and hassle-free - make a study group with your classmates, but make sure you carry ethics with you all the time, meaning absolutely NO-CHEATING. (You do not want to flunk your classes, do you?)Having said that, the problem is not bad at all. Try a little harder, think more and bingo there you go with a perfect answer, and Sandy123 scoring the perfect score in every assignment. :DNo more digression! Since the speed and the wavelength are given, you can easily calculate the Time Period for each cycle using the formula: wavelength (lambda) = speed (v) * TOnce you find T, calculate the number of cycles to cover 1000m by diving total distance (1000) by the distance/cycle. [ With the given amplitude, you can easily calculate the distance/cycle]Lastly for the total time taken, multiply the total number of cycles and the T for each cycle.Now, your work is to plug numbers into the formula and let me know how it goes.G'luck!-Grace Last edited: 27-Jan-10 10:18 PM
