The pulley shown has a radius of 12.02 cm. Suppose it takes 16 sec for 61 cm of belt to go around the pulley. (a) Find the linear speed of the belt in centimeters per second (b) Find the angular speed of the pulley in radians per second 12.02 cm (a) The linear speed of the roller is cm per second. (Type an integer or decimal rounded to the nearest tenth as needed.) (b) The angular speed of the roller...

A mass m hangs on the end of a cord around a pulley of radius a
and moment of inertia I, rotating
with an angular velocity w, as shown in the figure below. The rim
of the pulley is attached to a
spring (with constant k). Assume small oscillations so that the
spring remains essentially
horizontal and neglect friction so that the conservation of energy
of the system yields:
1/2mv^2 +1/2Iw^2+1/2kx^2-mgx=C,
where w=v/a, C=const, x+displacement from equilibrium
Find the natural...
