An Atwood machine, similar to an elevator with a counter-weight, is initially at rest. On one side is a mass of 2.0 kg and on the other side is a masss of 1.00 kg. A massless cord that passes over a pulley connects the two weights. The pulley has a mass of 4.00 kg, a radius of 0.2m, no friction, and can be treated as a uniform disk. When the heavier mass has fallen 0.50m, what is its linear speed in m/s

One kind of elevator has the elevator car hanging from a cable, which then passes over a pulley and connects to a counterweight, as shown in (Figure 1). The mass of a fully-loaded elevator (that is, the elevator and all its passengers) is 1850 kg , the mass of the counterweight is 1500 kg , and the pulley has a radius of 0.4 m and a mass of 400 kg . A motor drives the motion of the elevator by...
A sphere of radius R can rotate about a vertical axis on frictionless bearings (see figure below). Let the rotational inertia of the sphere behe.A massless cord passes around the equator of the sphere, overs pulley with rotational inertial and radius r, and is attached to a small object of mass m. There is no friction on the pulley's axle and the cord does not slip on the pulley. Att 0, the mass m has speed Vo The system is...
please do part B! Part 2: Problems Problem 1:12 points An Atwood machine is made of two masses m! = 0 15 kg and m2 = 0 1 kg attached to lightweight (i.e. massless) string placed over a pulley. As always the string does not stretch. The pulley is made of a disk of mass M-0.5 kg and radius R = 0.1 m. The two masses are initially at rest at the same height yinitial-0.75 m above the ground. Use...

A sphere of radius R can rotate about a vertical axis on frictionless bearings (see figure below). Let the rotational inertia of the sphere be Isphere. A massless cord passes around the equator of the sphere, over a pulley with rotational inertia I pulley and radius r, and is attached to a small object of mass m. There is no friction on the pulley's axle and the cord does not slip on the pulley. At t = 0, the mass...
Two blocks are connected by a string that passes over a frictionless pulley, as shown in the figure. The pulley has a mass of mp = 2.00 kg, and can be treated as a uniform solid disk that rotates about its center. Block A, with a mass = 3.00 kg, rests on a ramp measuring 3.0 m vertically and 4.0 m horizontally. Block B hangs vertically below the pulley. Note that you can solve this exercise entirely using forces, torques,...
Fall I- 2017 Exam2-GeneralPhysics」 00 5 of 6 problems,A 6" problem will count towards extra credit, 1. Conservation of Linear Momentum gure 1. A pendulum of string length 20 cm and bob mass of 1 kg at its end, starts from rest. The pendulum -on with a block of mass 2 kg, initially at rest. The collision is swings down a quarter of a circle and collides head elastic. Neglect the mass of the string. (a) Find the speed of...
Hi, I really just need help with number 8. The rest of the question is provided for context, thanks! 6.10 pts) A patient with a broken leg was placed in traction using the system shown below at left. Once the cast is off of the foot, the system can be modeled as shown at right where mi is the mass of the cast. In a most unfortunate incident, the cast slips off of the patient's foot and is flung by...
