A student is riding on the edge of a spinning merry-go-round (MGR); he is sitting cross-legged on the MGR edge, facing radially outwards, and holding a sandbag so that if he releases the sandbag it will fall onto the ground just beyond the MGR edge. Suddenly, he releases the sandbag; it falls to the ground where it sticks and thus stops moving. Consider the following statements concerning angular momentum, as measured about the central vertical axle of the merry-go-round, in...

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 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....

Two disks are mounted (like a merry-go-round) on low-friction bearings on the same axle and can be brought together so that they couple and rotate as one unit. The first disk, with rotational inertia 3.25 kg m2 about its central axis, is set spinning counterclockwise (which may be taken as the positive direction) at 181 rev/min. The second disk, with rotational inertia 7.95 kg.m2 about its central axis, is set spinning counterclockwise at 879 rev/min. They then couple together. (a)...

5. A 3.0 m diameter merry-go-round (mass 200 kg) is spinning at 10 rpm. A child of 30.0 kg runs tangent to the merry-go-round at 2.0 m/s, in the opposite direction that it is turning, and jumps onto the outer edge. Calculate the merry-go-round's angular velocity, immediately after the child jumps on.

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?

equipment. A 3.0-m-diameter merry-go-round with a mass of 300 kg is spinning at 15 rpm . John runs tangent to the merry-go-round at 4.8 m/s , in the same direction that it is turning, and jumps onto the outer edge. John's mass is 30 kg. Part A: What is the merry-go-round's angular velocity, in rpm, after John jumps on?
