Astudent holds one end of a thread, which is wrapped around a cylindrical spool, as shown above. the student then drops the spool from a height h above the floor, and the thread unwinds as it falls. the spool has a mass m and a radius r, and the thread has negligible mass. the spool can be approximated as a solid cylinder of moment of inertia i = 1 mr2. express your answers in terms of m, r, h, and fundamental constants. at time t = 0, the spinning spool lands on the floor without bouncing and comes free from the thread. it continues to spin, but slips on the floor's surface while doing so. assume a constant coefficient of sliding friction m. (c) calculate the angular velocity of the spool as a function of time t.
