A weight with mass mw=150 g is tied to a piece of thread wrapped around a spool, which is suspended in such a way that it can rotate freely. When the weight is released, it accelerates toward the floor as the thread unwinds. Assume that the spool can be treated as a uniform solid cylinder of radius R=4.00 cm and mass Ms=200 g. Find the magnitude ?a of the acceleration of the weight as it descends. Assume the thread has negligible mass and does not slip or stretch as it unwinds. Use ?=9.81 m/s2. Find the tension T in the thread.

A plank with a mass M = 6.00 kg rests on top of two identical, solid, cylindrical rollers that have R = 5.00 cm and m = 2.00 kg. The plank is pulled by a constant horizontal force Fs of magnitude 6.00 N applied to the end of the plank and perpendicular to the axes of the cylinders (which are parallel). The cylinders roll without slipping on a flat surface. There is also no slipping between the cylinders and the plank. a. Find the initial acceleration of the plank at the moment the rollers are equidistant from the ends of the plank. b. Find the acceleration of the rollers at this moment. c. What friction forces are acting at this moment?
A uniform drawbridge must be held at a 37° angle abovethe horizontal to allow ships to pass underneath. The drawbridge weighs45,000 N and is 14.0 m long. A cable is connected 3.5 m from thehinge where the bridge pivots (measured along the bridge) and pullshorizontally on the bridge to hold it in place. If the cable suddenly breaks, what is the magnitude of the angular acceleration of the drawbridge just after the cable breaks?

Please answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE. Korean Bell. A bell-ringer hits a massive bell using a 21-kg cylindrical log. The log is supported by two cords that behave like a rod. He normally uses a 200-N force P, at 60° with respectto the log, to push the log towards the bell. Assuming the two supports have negligible mass, determine the (a) normal and tangential accelerations of the log, and the (b) force developed at each support, at the instant when the cords are vertical and the angular velocity of the log is ω = 6 rad/s, CW. *kindly, include all necessary FBDs and solutions*if necessary, use g=9.81 m/s2
