QUESTION 1 Question 1. Select the best answer regarding your observation from step 1.9. a. both s(t) and b(t) appear as identical sine waves b. both s(t) and b(t) appear as identical cosine waves c. both s(t) and b(t) appear as cosine waves; however, their amplitudes differ d. s appears as a sine wave while b appears as a cosine wave; both have different amplitudes

Amerry-go-round of radius r, shown in the figure, is rotating at constant angular speed. the friction in its bearings is so small that it can be ignored. a sandbag of mass m is dropped onto the merry-go-round, at a position designated by r. the sandbag does not slip or roll upon contact with the merry-go-round. how would you rank the following different combinations of m and r on the basis of the angular speed of the merry-go-round after the sandbag "sticks" to the merry-go-round from largest to smallest. a) m = 10kg, r = 0.25r b) m = 20kg, r = 0.25r c) m = 10kg, r = 0.50r d) m = 10kg, r = 1.0r e) m = 15kg, r = 0.75r f) m = 40kg, r = 0.25r
