NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Two small disks A a
nd B of mass 2 kg and 1 kg, respectively, may slide on a horizontal and frictionless surface. They are connected by a cord of negligible mass and spin about their mass center G. At t = 0, G is moving with the velocity v0¯¯¯ and its coordinates are x0¯¯¯= 0 and y0¯¯¯= 1.89 m. Shortly thereafter, the cord breaks and disk A is observed to move with a velocity vA= (5 m /s)j in a straight line and at a distance a = 2.56 m from the y axis, while B moves with a velocity vB= (7.2 m/s)i - (4.6 m/s)j along a path intersecting the x axis at a distance b =7.48 m from the origin O

Answer:
The power consumed by the air filter is 9.936 watts
Explanation:
It is given that, the secondary coil of a step-up transformer provides the voltage that operates an electrostatic air filter.
Turn ratio of the transformer,
Voltage of primary coil,
Current in the secondary coil,
The power consumed by the air filter is :
...........(1)
For a transformer,
So,
So, the power consumed by the air filter is 9.936 watts. Hence, this is the required solution.
Part 1
If water does not spill at the top point of the circular motion then for the minimum speed condition we can say normal force will be zero at the top position
given that
R = 1 m
g = 9.8 m/s^2
now from above equation we have
Part b)
for minimum value of angular speed we will have
