Collapse question part Part 1 (a) At location A: What is the direction of the gravitational force exerted on the comet by the star? Is the parallel component of the net force on the comet zero or nonzero? Is the perpendicular component of the net force on the comet zero or nonzero? Is , the rate of change of the magnitude of the comet's momentum, positive, negative, or zero? Is , the direction of the comet's momentum, changing or not changing?

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
