A horizontal 100 kg merry-go-round of radius 1.80m is started from rest by a constant horizontal force of 50 N applied tangentially to the merry-go-round. Two children o mass 50 kg are riding the merry-go-round, one of which is standing 0.75 m from the of rotation and the other is 0.5 m from the axis. (a) (5 points) Calculate the moment of incrtia of the system Assume the MR? and that the two child round has a moment of inertia...
please help Extra credit (10 points each) 1. A horizontal merry-go-round has a weight of 600-N and radius of 2.00 m. It is started from rest by a constant horizontal force of 50.0 N applied tangentially to the merry-go- round. Treat the merry-go-round as a solid disk. a) What is the moment of inertia of the merry go round, in kg m?? b) What is the angular acceleration (in rad/sec)? c) What is its angular speed after 4.00 seconds (in...
A 90-kg merry-go-round of radius 2.0 m is spinning at a constant speed of 20 revolutions per minute. A kid standing on the ground decides to bring the merry-go-round to rest and applies a force of 10.0 N tangentially to the merry-go-round. If the merry-go-round is modelled as a solid cylinder, (A) calculate its moment of inertia. (B) What is the angular acceleration of the merry-go-round? (C) How many revolutions will the merry-go-round complete until it finally stops? 1) [25...
A merry-go-round, which may be approximated as a solid disk of mass 90.0 kg and radius 2.00 m, is originally at rest but free to rotate in the horizontal plane about its center. A child applies an external force of 20.0 N tangentially to the outer edge of the merry-go-round, for a duration of 15.0 s. (a) What is the final angular velocity of the merry-go-round? (b) What is the average power supplied by the child in the process? (c)...
