Again, looking down from a stationary tree branch, a merry-go-round with a 1.2meter radius spins in a counter-clockwise direction with an angular velocity of 1 radian per sec-ond. From your viewpoint, abird of mass 0.4kg flies in a straight lineover the axis of the merry-go-roundat a uniform speed of 3m/s. a)Draw the trajectory of the bird as seen from your stationary tree branch. b)Draw the trajectory of the bird as seen from an observer on the merry-go-round. c)Consider three instants: i. When the bird first crosses the outer edge of the merry-go-round; ii. When the bird crosses the center of the merry-go-round; iii. When the bird finally crosses the outer edge of the merry-go-round.
