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 starts from rest at the top of
the well and falls for 2.84 s before hitting the water, how far
does it fall?
m
The tension we calculate as follows:
Using Newton's second law, we have the acceleration is:

One end of a cord is attached to and wrapped around a solid, frictionless cylinder of mass M=4.1 kg. The other end of the cord is attached to a bucket of mass 1.1 kg. A brake applied to the cylinder is released, allowing the bucket to fall downward. Find the acceleration of the bucket in m/s2.
A bucket of water of mass 15.7 kg is suspended by a rope wrapped around a windlass, that is a solid cylinder with diameter 0.280 m with mass 11.4 kg . The cylinder pivots on a frictionless axle through its center. The bucket is released from rest at the top of a well and falls a distance 10.6 m to the water. You can ignore the weight of the rope. Part A What is the tension in the rope while...
A bucket of water of mass 14.4 kg is suspended by a rope wrapped around a windlass, that is a solid cylinder with diameter 0.350 m with mass 13.0 kg . The cylinder pivots on a frictionless axle through its center. The bucket is released from rest at the top of a well and falls a distance 10.0 m to the water. You can ignore the weight of the rope. Take the free fall acceleration to be g = 9.80...

A rope of negligible mass is wrapped around a 225-kg solid cylinder of radius 0.400 m. The cylinder is suspended several meters off the ground with its axis oriented horizontally, and turns on that axis without friction. (a) If a 75.0-kg man takes hold of the free end of the rope and falls under the force of gravity, what is his acceleration? m/s2 (b) What is the angular acceleration of the cylinder? rad/s2
