a merry-go-round in the park has a radius of 2.5 m and rotational inertia of 1000 kg*m^2. a child pushes the merry-go-round with a constant force of 50 N applied at a point tangent to the edge. a frictional torque of 12 N*m acts at the axle of the merry-go-round. what is the rotational acceleration of the merry-go-round while the child is pushing? at this rate, what will the rotational velocity of the merry-go-round be after 12 s if it...

Two children standing on opposite sides of a merry-go-round are trying to rotate it. They each push in opposite directions with forces of magnitude 11.5 N. (a) If the merry-go-round has a mass of 171 kg and a radius of 1.54 m, what is the angular acceleration of the merry-go-round? (Assume the merry-go-round is a uniform disk.) rad/s2

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?

Three children are riding on the edge of a merry-go-round that has a mass of 105 kg and a radius of 1.70 m. The merry-go-round is spinning at 18.0 rpm. The children have masses of 22.0, 28.0, and 33.0 kg. If the 28.0 kg child moves to the center of the merry-go-round, what is the new angular velocity in revolutions per minute? Ignore friction, and assume that the merry-go-round can be treated as a solid disk and the children as...
