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...
A child sitting 1.90 m from the center of a merry-go-round moves with a speed of 2.15 m/s . Part A: Calculate the centripetal acceleration of the child. Part B: Calculate the net horizontal force exerted on the child. (mass = 28.5 kg )
A playground merry-go-round has a radius of R = 4.0m and has a moment of inertia I_cm = 7.0 times 10^3 kg middot m^2 about an axis passing through the center of mass. There is negligible friction about its vertical axis. Two children each of mass m = 25kg are standing on opposite sides a distance r_0 = 3.0m from the central axis. The merry-go-round is initially at rest. A person on the ground applies a constant tangential force of...
Part A Max (15 kg) and Maya (12 kg) are riding on a merry-go-round that rotates at a constant speed. Max is sitting on the edge of the merry-go-round, 2.4 m from the center, and Maya is 1.2 m from the center. Considering Max and Maya to be one system of masses, what is their moment of inertia measured with respect to the center of the merry-go-round? O 1500 kg.m2 0 17 kg-m2 O50 kg.m2 O 104 kg-m2 86 kg-m2...
A playground merry-go-round has radius 2.50 m and moment of inertia 2000 kg⋅m2 about a vertical axle through its center, and it turns with negligible friction. part a A child applies an 23.5 N force tangentially to the edge of the merry-go-round for 22.0 s . If the merry-go-round is initially at rest, what is its angular speed after this 22.0 s interval? part b How much work did the child do on the merry-go-round? part c What is the...
How large must the force of friction be in order to keep a 75kg person in place on a merry go round which is revolving one every 4 seconds. The radius of the merry go round is 1.4m. b. If the coefficient of friction is 0.65, how fast would this person have to spin in order to be thrown off the merry go round? (Give your answer in m/s) c. At this speed, what is the period of revolution?
please help part B how do you find delta theta?
part C help
1. Two children running along the side of a merry-go-round, push on it to spin it faster, as shown to the right. The first child pushes with E 24.0 N, applied tangent to the merry-go-round at its edge. The second child pushes with Fa-13.O N, also applied tangent to the edge of the merry-go-round. The merry-go-round is free to rotate about its center, has a mass of...
If you move at the speed of light, how does a light beam move relative to you? Why?
4. A child sitting 2 meters from the center of a merry-go-round moves at a speed of 2 m/s.

A child pushes her friend (m = 25 kg) located at a radius r = 1.5 m on a merry-go-round (rmgr = 2.0 m, Imgr = 1000 kg*m2) with a constant force F = 90 N applied tangentially to the edge of the merry-go-round (i.e., the force is perpendicular to the radius). The merry-go-round resists spinning with a frictional force of f = 10 N acting at a radius of 1 m and a frictional torque τ = 15 N*m...
