Given the same conditions as the previous problem (see below), find the angular velocity of the disk at the instant 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 4.33 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 4.0 rotations before hitting the floor The time from release to when the mass strikes the floor is 6.2 seconds. Assume constant acceleration. Include units using radians Use the following format for writing powers positive s^2 or negative s^(-2).
