A Blu-ray disc has a mass of 20.0 g and a diameter of 120. mm. It takes 2.22 seconds for the Blu-ray player to get the disk up to speed from rest. Assume the operating speed of the Blu-ray disc is 10000 rpm (rotations per minute). Provide a diagram of the situation with coordinates. Calculate: a) Final angular momentum b) Work done to get disc up to speed

    The outside diameter of the playing area of an optical Blu-ray disc is 11.75 cm, and the inside diameter is 4.50 cm. When viewing movies, the disc rotates so that a laser maintains a constant linear speed relative to the disc of 7.30 m/s as it tracks over the playing area. 1) What is the average angular acceleration of a Blu-ray disc as it plays an 6.0-h set of movies? (Assume the disk is scanned starting at its inner radius...

    3. A U.S. quarter with a mass of 5.67 grams is sitting on a 12-inch (30.48 cm) diameter vinyl record on an old 78 revolution-per-minute (rpm) record player's turntable. The quarter is half way between the record's center and outer edge and the coefficient of static friction (As) between the quarter and record is 0.35. The record player (aka Victrola) has an old motor and it takes 90 seconds to speed up to 78 rpm from zero rpm. a. How...

    2. Conan the Barbarian has been captured and forced to turn a massive grinding wheel - a 1200 kg disk, 25 m in diameter. Starting from rest, it takes Conan 1.0 complete revolution to get the wheel up to its maximum angular velocity of 16.0 rpm. How much force does Conan exert (tangent at the edge of the wheel), getting the wheel up to speed?

    1. Three children are riding on the edge of a merry‑go‑round that has a mass of 105 kg and a radius of 1.80 m. The merry‑go‑round is spinning at 22.0 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...
