The torques will always be equal when two children are pushing a merry-go-round in opposite directions....
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
Three children are pushing on a merry-go-round in order to get it to rotate. Two children are pushing clockwise while the third child pushes counter clockwise. Derive an expression for the net torque.
6. (25 points) The following question examines the motion of two children on a merry-go- round. You may treat the children as point particles with mass m and the merry-go-round as a disk with mass M and radius R. The moment of inertia of a disk is Idisk MR2 0wn o r Ve n e r (a) Calculate the total energy of the system if the two children are at the edge of the merry- go-round and the merry-go-round is...
A child is pushing a merry-go-round. The angle through which the merry-go-round has turned varies with time according to ?(t)=?t+?t3, where ?= 0.383 rad/s and ?= 1.40
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.
Three children are riding on the edge of a merry-go-round that has a mass of 105 kg and a radius of 1.60m. The merry-go-round is spinning at 16.0 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 point...
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...
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= 0.394 rad/s and β= 1.25×10−2 rad/s3. Calculate the angular velocity of the merry-go-round as a function of time. Express your answer in terms of the variables β, γ, and t.
