A 1.0 kg ball and a 2.0 kg ball are connected by a 1.3-m-long rigid, massless rod. The rod is rotating cw about its center of mass at 17 rpm . What torque will bring the balls to a halt in 4.6 s ?
Added by Donna B.
Step 1
āā¢ Let mā = 1.0 kg and mā = 2.0 kg, and let the rodās total length be L = 1.3 m. āā¢ If rā is the distance from mā to the COM and rā is the distance from mā to the COM, then by definition of the center of mass, āāmāĀ·rā = māĀ·rā. āā¢ Also, the two distances add up to Show moreā¦

A 1.0 kg ball and a 2.0 kg ball are connected by a 1.1-m-long rigid, massless rod. The rod is rotating clockwise about its center of mass at 16 rpm. What torque will bring the balls to a halt in 4.0 s?
A 1.0 kg ball and a 2.0 kg ball are connected by a 1.0-m-long rigid, massless rod. The rod is rotating cw about its center of mass at 25 rpm .What torque will bring the balls to a halt in 4.4 s ?
