a bug is sitting on the rim of a garden hose reel at radius 0.33 m from the axis of rotation. A person begins to pull the hose with a linear acceleration of 0.75 m/s^2, with the hose wrapped around the reel at a radius 0.10m. What linear acceleration does the bug experience as the reel begins to rotate?

A solid, frictionless cylinder reel of mass M = 3.13 kg and radius R = 0.437 m is used to draw water from a well (see Figure (a)). A bucket of mass m = 2.04 kg is attached to a cord that is wrapped around the cylinder. (Indicate the direction with the sign of your answer.) (a) Find the tension T in the cord and acceleration a of the bucket. T = N a = m/s2 (b) If the bucket...
A device is made of a wheel with an inner drum and is mounted on a frictionless axle so it does not translate but can rotate about its centre. As indicated in the figure, this device is used to lift a 30.0 kg box. The outer radius R of the device is 0.500 m and the radius of the inner drum is 0.200 m. A constant horizontal force F of magnitude 140 N is applied horizontally, as shown, to a...
An object with a mass of m - 4.80 kg is attached to the free end of a light string wrapped around a reel of radius R - 0.275 m and mass of M 3.00 kg. The reel is a solid disk, free to rotate in a vertical plane about the horizontal axis passing through its center as shown in the figure below. The suspended object is released from rest 6.80 m above the floor. (a) Determine the tension in...
A cord s wrapped around the rim of a solid uniform wheel 0.22 m in radius and of mass 8.60 kg . A steady horizontal pull of 50.0 N to the right is exerted on the cord, pulling it off tangentially from the wheel. The wheel is mounted on frictionless bearings on a horizontal axle through its center. Part A Compute the angular acceleration of the wheelPart B Compute the angular acceleration of the part of the cord that has already been pulled...
The reel shown in Figure P10.70 has radius R and moment of inertia I. One end of the block of mass m is connected to a spring of force constant k and the other end is fastened to a cord wrapped around the reel. The reel axle and the incline are frictionless. The reel is wound counterclockwise so that the spring stretches a distance d from its unstretched position and is then released from rest. (a) Find the angular speed...
m2 0.600 m Figure P8.36 (c8p36). A cylindrical 8.00-kg reel with a radius of 0.60 m and a frictionless axle, starts from rest and speeds up uniformly as a 1.00-kg bucket falls into a well, making a light rope unwind from the reel (Fig. P8.36). The bucket starts from rest and falls for 6.00s. (a) What is the linear acceleration of the falling bucket? Submit Answer Tries 0/8 (b) How far does it drop? Submit Answer Tries 0/8 (c) What...
A flywheel (a uniform solid cylinder of radius 0.25 m and mass 80 kg) is initially at rest, but free to rotate about the axis through its center. A belt wrapped around it is pulled off horizontally, providing a tangential force of 45 N to the outer rim of the flywheel for 2.00 s. Calculate the final kinetic energy of the wheel.
A uniform disk of radius 0.551 m and unknown mass is constrained to rotate about a perpendicular axis through its center. A ring with same mass as the disk\'s is attached around the disk\'s rim. A tangential force of 0.229 N applied at the rim causes an angular acceleration of 0.103 rad/s2. Find the mass of the disk.
20.) A circular disc of mass M =500 gm and radius R = 20 cm is rotating about an axis perpendicular to it and passing through its centre. The initial angular speed of rotation of the disc is 30 rad/s. A bug of mass m = 25 gm which was originally on the disc at the rotating axis crawls outward and stops when it is 5 cm from the rim of the disc Calculate the new speed of rotation of...
