- Two students are on opposite sides of a merry-go-round of radius 2.1 m and mass 64 kg. One pushes tangent to the outer edge in the clockwise direction with a force, F. The other pushes in the counter-clockwise direction with a force of 33 N. Model the merry-go-round as a disc (I=1/2MR2). If the angular acceleration of the merry-go-round is 0.32 rad/s2, what is the magnitude of force F?

You are sitting on a merry-go-round of mass 200 kg and radius 2m that is at rest (not spinning). Your mass is 50 kg. Your friend pushes the edge of the merry go round with 100 N of force, applied at a 90 deg angle. (hint: the merry-go-round is a disk). a. How much torque did your friend apply? b. What is your angular acceleration if you are sitting in the middle of the merry-go-round? c. What is your angular...

5. A 3.0 m diameter merry-go-round (mass 200 kg) is spinning at 10 rpm. A child of 30.0 kg runs tangent to the merry-go-round at 2.0 m/s, in the opposite direction that it is turning, and jumps onto the outer edge. Calculate the merry-go-round's angular velocity, immediately after the child jumps on.

A merry-go-round is a common piece of playground equipment. A 2.8-m-diameter merry-go-round with a mass of 260 kg is spinning at 22 rpm. John runs tangent to the merry-go-round at 5.0 m/s, in the same direction that it is turning, and jumps onto the outer edge. John's mass is 39 kg. What is the merry-go-round's angular velocity, in rpm, after John jumps on?

Again, looking down from a stationary tree branch, a merry-go-round with a 1 meter radius spins in a counter-clockwise direction with an angular velocity of 1 radian per second. From your viewpoint, a bird of mass 0.2kg flies in a straight line over the axis of the merry-go-round at a uniform speed of 2m/s. Consider three instants: when the bird first crosses the outer edge of the merry-go-round; when the bird crosses the center of the merry-go-round; and, finally, when...
