A weight with mass mw=150 gmw=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=3.00 cmR=3.00 cm and mass Ms=200 gMs=200 g . Find the magnitude aa 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 g=9.81 m/s2.g=9.81 m/s2.

Find the acceleration? and tension in the thread?

The mass is connected with a string and wrapped around the spool

So here we can say that the force on the mass is due to weight and the tension in string so as per the force equation we have:

A cord is wrapped around a pulley of diameter 0.320 m with the free end tied to a weight. That weight is allowed to descend at constant acceleration. A stopwatch is started at the instant when the weight reaches a speed of 0.023 m/s. At a time of t = 1.50 s, the weight has dropped an additional 0.080 m. Calculate the magnitude of the centripetal acceleration of any point on the circumference of the pulley at t = 4.0...

String is wrapped around an object of mass M = 0.3 kg and moment of inertia I = 0.01 kgÂ·m2. You pull the string with your hand straight up with some constant force F such that the center of the object does not move up or down, but the object spins faster and faster (see the figure). This is like a yo-yo; nothing but the vertical string touches the object. When your hand is a height y0 = 0.26 m...

(b) Background radiation gives about 20 spurious counts per minute in a typical counter used for carbon dating. If the number of carbon decays per minute is much smaller than this, it is difficult to accurately determine the age of a sample. Estimate the maximum age (in years)...
