A 1400 kg car is traveling at 24 m/s around a curve with a radius of 115 m. What is the angular momentum of the car?

An object of mass 2.75 kg is moving with a velocity v = (3.8of – 5.10k) m/s. What is the angular momentum of the mass relative to the origin when it is at the location (1.50, -1.50, 1.50) m? (Express your answer in vrector form )

Three children are riding on the edge of a merry‑go‑round that has a mass of 105 kg and a radius of 1.70 m . The merry‑go‑round is spinning at 20.0 rpm. The children have masses of 22.0, 28.0, and 33.0 kg. If the 28.0 kg child moves to the center of the merry‑go‑round, what is the new angular velocity in revolutions per minute? Ignore friction, and assume that the merry‑go‑round can be treated as a solid disk and the children as point masses.   final angular velocity:   rpm

A 1000 kg car moves with a speed of 50 m/s on a circular track of radius 100 m. What is the magnitude of its angular momentum (in kg m2/s) relative to the center of the race track?

A phonograph record of Mozart's N.41 Symphony is whirling around at 103 rpm. Two balls, each of mass 1 × 10-1 kg, are sitting on the disk, and are at rest with respect to the disk. The first one, "ball 1" sits the end of the paper label, 5 cm from the center of the record. The second one, 2, sits 10 cm out from the center, on the very edge of the record, as shown in the figure. What is the ratio of the friction forces acting on them? Ratio = (friction on ball 2/friction on ball 1) ball a) 0.5 b) 2 c) 1 d) 0.25 e) Not enough information to determine. 4.

How fast, in rpm, would a 129 g, 44.0 cm diameter beach ball have to spin to have an angular momentum of 0.115 kg*m2/s?

A fisherman is reeling in a fish at a speed of 0.42 m/s. The fishing line is being spooled onto a reel whose radius is 0.017 m. What is the angular speed of the reel?

Three children are riding on the edge of a merry‑go‑round that has a mass of 105 kg and a radius of 1.40 m. The merry‑go‑round is spinning at 20.0 rpm. The children have masses of 22.0, 28.0, and 33.0 kg. If the 28.0 kg child moves to the center of the merry‑go‑round, what is the new angular velocity in revolutions per minute? Ignore friction, and assume that the merry‑go‑round can be treated as a solid disk and the children as point masses.
