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?

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...
You are sitting on a merry-go-round that is accelerating with a constant angular acceleration. As the merry-go-round goes faster, which of the following is not increasing? A)Angular Velocity B)Tangential Acceleration C)Centripetal Acceleration D) Tangential Velocity E) All are increasing
A passenger sits in a seat of a spinning merry-go-round. The person is 15 meters from the merry-go-round’s center going at a speed of 5 m/s. What is the passenger’s centripetal acceleration?
1. (10 pts) A merry-go-round is spinning as indicated in the figure. The merry-go-round is slowing down. What are the direction and units of the angular momentum, angular velocity, angular acceleration? What is the direction and units of the centripetal acceleration of someone sitting on the outside? How would you find how long the merry-go-round takes to stop? Direction & Units of Angular Momentum: Direction & Units of Angular Velocity: helly Butward Up + Counterclockwise Direction & Units of Angular...
A child is sitting on the outer edge of a merry-go-round that is 18 m in diameter. If the merry-go-round makes 8.8 rev/min, what is the velocity of the child in m/s? 5.8 m/s 8.3 m/s 1.3 m/s 16.6 m/s
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...
A child sitting 2.0 m from the center of a merry-go-round moves with a speed of 1.10 m/s Calculate: the centripetal acceleration of die child and the net horizontal force exerted on the child (mass = 22.5 kg) Calculate the centripetal acceleration of the Earth in its orbit around the sun and the net force on the Earth Whit exerts this force on the Earth? Assume that the Earth orbit is a circle of radius 1.50 times 10^11 m What...
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 )
26. A 35 kg child is sitting at the edge of a 750 kg merry-go-round (assume it is a solid uniform cylinder or disk) with radius 2.0 m which is rotating once every 30 seconds. a. Calculate the angular velocity of the merry-go-round. 0.21 rad's b. Calculate the speed of the child. 0.42 m/s C. Calculate the angular momentum of the merry-go-round and child together. 343.5 d. If the child moves into the center of the merry-go-round, what will the...
