Physics help, tension in cable.?
A 24 kg loudspeaker is suspended 3.0 m below the ceiling by two cables that are each 20 degrees from vertical.
Part A -
What is the tension in the cables?
Express your answer using two significant figures.
T = N
The vertical component of tension for each cable is
T cos 20
Thus,
( 24 kg ) ( 9.8 m/s^2 ) = 2 T cos 20
T = 130 N
