Answer:
The momentum of block B = 27 Kg m/s
Explanation:
Given,
The initial momentum of block A, MU = 15 Kg m/s
The final momentum of block A, MV = -12 Kg m/s
Consider the block B is initially at rest.
Therefore, the initial momentum of block B, mu = 0
According to the laws of conservation of linear momentum, the momentum of the body before impact is equal to the momentum of the body after impact.
<em> MU + mu = MV + mv</em>
15 + (0) = (-12) + mv
mv = 15 + 12
= 27 Kg m/s
Hence, the momentum of the block B after impact is, mv = 27 Kg m/s
The speed of the bucket is v = 4.61 m/sec
For the free body diagram, and apply Newton's second law:
T - mg = m(v2/r)
Plug in known values,
25 - 1.00*g = 1.00(v2/1.40)
Solve for v,
v = 4.61 m/sec
What is motion?
Motion is the change of position or direction of a body over time. Movement along a line or curve is called a translation. Movement that changes the direction of the body is called rotation. In both cases, all points on the body have the same speed (directional speed) and the same acceleration (time rate of change of speed). The most common motion combines both translation and rotation.
There are 6 types of motion

'Retina' of the eye contains the visual receptors.
Aluminum because it is the best heat conductor. Think of a wood floor, for example. In the morning, is it cold when you step on it? Soil doesn't conduct heat, it just dries up. Cork is an insulator, not a heat conductor.
