A play ground merry go round has a radius of 3.0 m and a rotational inertia of 600 kg x m2. A 25 g child pushes and jumps on the edge. it is then spinning at 0.80 rad/s. the child then crawls from the rim to the very center of the merry go round. Now how fast does it spin?

1.A playground merry-go-round has a radius of 3.0 m and a rotational inertia of 600 kgˑm2. It is initially spinning at 0.80 rad/s when a 20 kg child crawls from the center to the rim. When the child reaches the rim the angular velocity of the merry-go-round in rad/s is: 2.A picture P of weight W = 40 N is hung by two strings as shown. The magnitude of the tension force of each string is T and θ=30°. The...
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...
Physics Q. A merry-go-round comprises a wooded disk of radius R=2 meters and rotational inertia 148kg·m2 . It rotates with an angular velocity of 2.5rad/s, with a small (point-like!) child of mass 10kg at its center. The child then crawls to the outside rim. What is the the angular velocity now?____rad/s please explain how to solve for this.
1.A flywheel rotating at 12 rev/s is brought to rest in 5 s. The magnitude of the average angular acceleration in rad/s2 of the wheel during this process is: 2.The coefficient of static friction between a certain cylinder and a horizontal floor is 0.50. If the rotational inertia of the cylinder about its symmetry axis is given by I = (1/2)MR2, then the magnitude of the maximum acceleration in m/s2 the cylinder can have without sliding is: 3.A playground merry-go-round...
28. II A 4.0-m-diameter playground merry-go-round with a moment of inertia of 400 kg m2, is freely rotating with an angu- lar velocity of 2.0 rad/s. Ryan, whose mass is 80 kg, runs on the ground around the outer edge of the merry-go-round in the opposite direction to its rotation. Still moving, he jumps directly onto the rim of the merry-go-round, bringing it (and himself) to a halt. How fast was Ryan running when he jumped on? A. 2.0 m/s...
Problem 3: A merry-go-round can be considered a uniform disk of mass 145 kg and radius 2.10 m free to rotate about a frictionless axis through its center. A 40.0 kg child stands at the edge and the system is initially rotating at 0.300 rad/sec. The child begins to walk around the edge of the merry-go-round with a velocity of 0.250 m/s relative to the ground in the direction of the rotation. What is the angular velocity of the merry-go-round...
(4) A playground ride, known as merry-go-round, consists of a disk with a mass of 40.0 kg and a radius of 1.80 m mounted on a frictionless axle. The frictionless axle is a vertical cylinder of radius kg, and has the same rotational axis as the disk. A child with a mass of 3.50 m/s on a line tangential to the outer rim of the disk and jumps onto the outer edge of the ride while it is at rest...
24. In the figure, a man pushes on the outside edge of a merry-go-round Merry-go-round with a constant 60 newton force. In so doing, he manages to increase the spin rate of the merry-go-round from rest to 3 rad/sec in 2 seconds. Assume the radius of the merry-go-round is 2 meters. What is its moment of inertia? maximum α
A 4.0-mm-diameter playground merry-go-round, with a moment of inertia of 400 kg⋅m2kg⋅m2 is freely rotating with an angular velocity of 2.5 rad/srad/s . Ryan, whose mass is 75 kgkg , runs on the ground around the outer edge of the merry-go-round in the opposite direction to its rotation. Still moving, he jumps directly onto the rim of the merry-go-round, bringing it (and himself) to a halt. How fast was Ryan running when he jumped on? How fast was Ryan running...
A playground merry-go-round of radius R = 2.20 m has a moment of inertia of I = 280 kgm2 and is rotating at 11.0 rev/min about a frictionless vertical axis. Facing the axle, a 21.0 kg child hops on to the merry-go-round and manages to sit down on its edge.
