43. In the Fletcher cart apparatus problem, a 1.0 kg object resting on a horizontal table is connected by a string to a 0.50 kg hanging object. The system is released from rest. the coefficient of kinetic friction between the 1.0 kg object and the table is 0.20. Determine the rate of acceleration of the system. ANS. 2.0 m/s E-11, P-31 44. In the Atwood machine experiment, a 3.0 kg object and a 1.0 kg object are connected by a string which masses over a pulley. The system is released from rest. Determine the rate of acceleration of the system. ANS. 5.0 m/s E-6, P-32
