Question

Given the same conditions as the previous problems and assuming friction-less conditions how long will it take the apparatus to go through an additional 10.0 rotations after the mass hits the floor? A vertical axis rotational apparatus shown is the apparatus we used in Laboratory. The apparatus has low friction, low mass rotating bracket that holds a disk. The disk has a diameter of 25.4 cm and a mass of 433 kg. The hub around which the string is wrapped is 4.76 cm in diameter. The apparatus is accelerated by a string wrapped around a circular hub at the center of the base of the apparatus. The string passes horizontally over a low friction low mass pulley to a hanging mass which fall toward the floor when released. When the hanging mass is released from rest the disk spins through 4.00 rotations before hitting the floor The time from release to when the mass strikes the floor is 9.90 seconds. Assume constant acceleration. Include units Use the following format for writing powers-positive s2 or negative sA(-2).
