a certain merry go round is accelerated uniformly from rest and attains an angular speed of 1.2 rad/s in the first 18 seconds. the force which causes this change in angular speed is 1000 n and applied along the tangential line to the edge of the merry go round. if the radius is equal to 1.5 m what is the moment of inertia of the merry go round?
4. Bugs Bunny and Daffy Duck are on a merry-go-round which is accelerated uniformly from rest. Bugs jumps off and increases the speed so that the ride attains an angular speed of 10.2 rad/s in the first 18 seconds. If the net applied torque is 1400 N m, what is the moment of inertia of the merry-go-round? Please show all work

A merry-go-round with moment of inertia 400 kg-m^2 and radius 2.0m is rotating with angular speed 0.50 rad/s in the clockwise direction about a fixed axis. A child of mass 40 kg runs tangentially to the merry-go-round with speed 3.0m/s and grabs onto the outside edge of the merry-go-round. a. What is the final angular velocity of the system (merry-go-round plus child)/ What is the final tangential speed of the child? b. What is the change in kinetic energy? c....
A child is pushing a merry-go-round. The angle through which the merry-go-round has turned varies with time according to θ(t) = γt + βt3, where γ = 0.40 rad/s and β = 0.012 rad/s3 Calculate the angular velocity of the merry-go-round as a function of time Calculate the average angular velocity ωav − z for the time interval t = 0 to t = 4.0 s.
