2.) A spinning, flat disk of radius 2.0 m has a tangential velocity at its edge of 4.5 m/s. a. Consider a point 0.33 meters from the axis of rotation. Find the tangential velocity there? b. Find the angular velocity at the edge of the disk. c. Find the angular velocity at that point 0.33 m from the axis of rotation. d. Find its centripetal acceleration at the edge. e. Using "b." above find in radians how far the point on the edge travels in 15 s.

Mud particles are released from the edge of a wheel of radius b moving on the ground. If the forward wheel speed is vo. Calculate the maximum height above the ground that the mud can reach. From which part of the wheel does the mud come out in this case? (It is necessary to assume that v > bg). = b +; 2g Утах 2v3 ANS

Current Attempt in Progress In an automatic clothes drier, a hollow cylinder moves the clothes on a vertical circle (radius r = 0.516 m), as the drawing shows. The appliance is designed so that the clothes tumble gently as they dry. This means that when a piece of clothing reaches an angle of 0 above the horizontal, it loses contact with the wall of the cylinder and falls onto the clothes below. How many revolutions per second should the cylinder make in order that the clothes lose contact with the wall when 0 = 57.0°?

A bucket of water with a mass of 2.36 kg is attached to a rope that is wound around a cylinder. The cylinder has a mass of 3.00 kg and is mounted horizontally on frictionless bearings. The bucket is released from rest. A) Find the speed of the bucket after it has fallen through a distance of 0.800 m. in m/s B) What is the tension in the rope? in N C) What is the acceleration of the bucket? Enter a positive value if the acceleration of the bucket is upward and enter a negative value if the acceleration of the bucket is downward. in m/s^2

A 50 g ball of clay is thrown from the left tangent to the top of a 2.0 kg, 30-cm-diameter sphere that spins at a frequency of 1 rev/s ccw about its center. Assuming that the clay sticks to the sphere, how fast must you throw the clay to ensure that the spinning sphere comes to a stop?
