Abucket of water with total mass 24 kg is attached to a rope, which in turn is wound around a 0.04-m radiuscylinder at the top of a well. the bucket is raised to the top of the well and released. the bucket is moving with aspeed of 4.0 m/s upon hitting the water surface in the well. what is the angular speed of the cylinder at thisinstant?

Angular speed,

Explanation:

Given that,

Total mass of the bucket, m = 24 kg

Radius of the cylinder, r = 0.04 m

Speed of the bucket, v = 4 m/s

To find,

The angular speed of the cylinder at this instant

Solution,

The relation between the linear speed and the angular speed is given by :

Therefore, the angular speed of the cylinder at this instant is 100 rad/s.

the answer is d. 4

hope this

also the more points you give the faster your questions get answered

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
