An green hoop with mass mh = 2.8 kg and radius Rh = 0.17 m hangs from a string that goes over a blue solid disk pulley with mass md = 2.4 kg and radius Rd = 0.08 m. The other end of the string is attached to a massless axel through the center of an orange sphere on a flat horizontal surface that rolls without slipping and has mass ms = 3.3 kg and radius Rs = 0.18 m. The system is released from rest.
*What is magnitude of the linear acceleration of the hoop?
*What is magnitude of the linear acceleration of the sphere?
*What is the magnitude of the angular acceleration of the disk pulley?
*What is the magnitude of the angular acceleration of the sphere?
*What is the tension in the string between the sphere and disk pulley?
*What is the tension in the string between the hoop and disk pulley?
*The green hoop falls a distance d = 1.55 m. (After being released from rest.)
*The green hoop falls a distance d = 1.55 m. (After being released from rest.)
How much time does the hoop take to fall 1.55 m?
*What is the magnitude of the velocity of the green hoop after it has dropped 1.55 m?
*What is the magnitude of the final angular speed of the orange sphere (after the green hoop has fallen the 1.55 m)?

A string is attached to the rim of a small hoop of radius r= 8.00×10−2 m and mass m = 0.180 kg and then wrapped several times around the rim. If the free end of the string is held in place and the hoop is released from rest and allowed to drop, as shown in the figure (Figure 1) , calculate the angular speed and the translational speed of the rotating hoop after it has descended h = 0.750 m...

A light string is wrapped
around the outside of a 2.0-kg-wheel whose radius is 75 cm. The
wheel has a frictionless axel that allows it to rotate but prevents
its center of mass from moving. Assume the moment of inertia of the
wheel is the same as that of a point particle of equal mass at the
same radius from the axel. The string is then attached to a 3.0-kg
hanging mass that is released from rest. While the mass...

A mass m hangs from a string. The string is attached to a frictionless pulley of mass M and is wrapped around it many times around it. The hanging mass is released from rest from a height h above the floor. The pulley is a uniform disk. use the rotational and linear second laws to find the acceleration of the mass as it falls. I got a = 2mg/(2m+M). Is this correct? If, so please explain
