Physics
A 1.00kg ball and a 2.00kg ball are connected by a 4.63m long rigid, massless rod. The rod is rotating clockwise about its center of mass at 33.0rpm. What torque will bring the balls to a halt in 4.07s? My Attempt: Center of Mass = [(1kg)(0m) + (2kg)(4.63m)]/(1kg+2kg) =9.26/3...

You need to bring all the x's to one side and all the numbers to the other: 2x/3 + 1/4= x/6 - 1/2 2x/3 - x/6 = -1/2 - 1/4 now lets multiply both sides by 3 to get rid of the 3 in the denominator of 2x/3 2x - 3x/6 = -3/2 - 3/4 now 3x/6 can simply down to x/2 2x - x/2 = -3/2...
