A 120-kg merry-go-round in the shape of a uniform, solid,
horizontal disk of radius 1.50 m is set in motion by wrapping a
rope about the rim of the disk and pulling on the rope. What
constant force would have to be exerted on the rope to bring the
merry-go-round from rest to an angular speed of 0.700 rev/s in 2.00
s? (State the magnitude of the force.)

A 100-kg merry-go-round in the shape of a uniform, solid, horizontal disk of radius 1.50 m is set in motion by wrapping a rope about the rim of the disk and pulling on the rope. What constant force would have to be exerted on the rope to bring the merry-go-round from rest to an angular speed of 0.900 rev/s in 2.00 s? (State the magnitude of the force.)
A rope is wrapped around the rim of a large uniform solid disk of mass 305 kg and radius 2.10 m. The horizontal disk is made to rotate by pulling on the rope with a constant force of 195 N. If the disk starts from rest, what is its angular speed in rev/s at the end of 2.65 s?
A rope is wrapped around the rim of a large uniform solid disk of mass 225 kg and radius 2.50 m. The horizontal disk is made to rotate by pulling on the rope with a constant force of 195 N. If the disk starts from rest, what is its angular speed in rev/s at the end of 1.65 s?
A rope is wrapped around the rim of a large uniform solid disk of mass 295 kg and radius 2.40 m. The horizontal disk is made to rotate by pulling on the rope with a constant force of 195 N. If the disk starts from rest what is its angular speed in rev/s at the end of 1.95 s?
A rope is wrapped around the rim of a large uniform solid disk of mass 315 kg and radius 1.60 m. The horizontal disk is made to rotate by pulling on the rope with a constant force of 195 N. If the disk starts from rest what is its angular speed in rev/s at the end of 2.95 s?
A rope is wrapped around the rim of a large uniform solid disk of mass 315 kg and radius 2.40 m. The horizontal disk is made to rotate by pulling on the rope with a constant force of 195 N. If the disk starts from rest what is its angular speed in rev/s at the end of 1.75 s?
A child exerts a tangential 42.2 N force on the rim of a disk shaped merry go round with a radius of 2.40 m. If the merry-go-round starts at rest and acquires an angular speed of 0.0860 rev/s in 3.50s, what is its mass?
A disk-shaped merry-go-round of radius 2.53 m and mass 185 kg rotates freely with an angular speed of 0.601 rev/s . A 55.4 kg person running tangential to the rim of the merry-go-round at 3.11 m/s jumps onto its rim and holds on. Before jumping on the merry-go-round, the person was moving in the same direction as the merry-go-round's rim. What is the final angular speed of the merry-go-round?
A disk-shaped merry-go-round of radius 2.83 m and mass 145 kg rotates freely with an angular speed of 0.641 rev/s. A 58.4 kg person running tangential to the rim of the merry-go-round at 3.31 m/s jumps onto its rim and holds on. Before jumping on the merry-go-round, the person was moving in the same direction as the merry-go- round's rim. What is the final angular speed of the merry-go-round?
A disk-shaped merry-go-round of radius 2.93 m and mass 125 kg rotates freely with an angular speed of 0.621 rev/s . A 65.4 kg person running tangential to the rim of the merry-go-round at 3.51 m/s jumps onto its rim and holds on. Before jumping on the merry-go-round, the person was moving in the same direction as the merry-go-round's rim. What is the final angular speed of the merry-go-round?
