Looking down from a stationary tree branch, a merry-go-round spins in a counter-clock- wise direction with an angular velocity of 1 radian per second. A squirrel of mass 0.6 kg reen Shot sits on the outer rim of the merry-go-round, at a radius of 4.0 meters. 10...53.13 PM a) What is the magnitude and direction of the vector @? b) What is the magnitude and direction of the Coriolis pseudo-force as felt by the squir- el? ereen Shot c) What is the magnitude and direction of the centrifugal pseudo-force as felt by the -12...9.02 PM squirrel? 2. Again, looking down from a stationary tree branch, a merry-go-round with a 1.2 meter radius spins in a counter-clockwise direction with an angular velocity of 1 radian per sec- ond. From your viewpoint, a bird of mass 0.4 kg flies in a straight line over the axis of the merry-go-round at a uniform speed of 3 m/s. id vaccine 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; gure 2a-c iii. When the bird finally crosses the outer edge of the merry-go-round. For each of the three moments, as seen by an observer on the merry-go-round, il- lustrate the direction of the centrifugal pseudo-force that seems to act on the bird. At what point is the centrifugal pseudo-force 0? You may use your sketch from part (b ). d) For instant (i), also illustrate on your sketch the direction of the Coriolis pseudo- reen Shot force acting on the bird (as seen with respect to the observer's merry-go-round 0...45.24 AM reference frame)
