Solution.

"m_1=60kg;"

"m_2=100kg;"

"l=4.50m;"

"\\upsilon=\\dfrac{2\\pi R}{T};"

The period of rotation of the needle:

"T=12 hr=43200 s;"

Needle rotation speed:

"v=\\dfrac{2\\sdot3.14\\sdot4.50m}{43200s}=0.0006541m\/s;"

Kinetic energy of needle movement:

"W_k=\\dfrac{mv^2}{2};"

"W_k=\\dfrac {160kg\\sdot( 0.0006541m\/s)^2}{2}=0.0000342J;"

Answer: "W_k=0.00003442J."
