g A block of mass mm is undergoing SHM on a horizontal, frictionless surface while attached to a light, horizontal spring. The spring has force constant kk, and the amplitude of the motion of the block is AA. Part APart complete The average speed is the total distance traveled by the block divided by the time it takes it to travel this distance. Calculate the average speed for one cycle of the SHM. Express your answer in terms of the variables mmm, AAA, and kkk. vavvav = 2Akm−−√π2Akmπ SubmitPrevious Answers Correct Part B How does the average speed for one cycle compare to the maximum speed vmaxvmax? Express your answer to three significant figures. vavvmaxvavvmax = 0.707 SubmitPrevious AnswersRequest Answer Incorrect; Try Again; 4 attempts remaining Part C Is the average speed more or less than half the maximum speed? Based on your answer, does the block spend more time while traveling at speeds greater than vmax/2vmax/2 or less than vmax/2vmax/2? Is the average speed more or less than half the maximum speed? Based on your answer, does the block spend more time while traveling at speeds greater than or less than ? The block spends more time traveling at speeds greater than vmax/2vmax/2. The block spends more time traveling at speeds less than vmax/2vmax/2.
