A massless rope passes over a pulley and weights are fixed on either end of the rope. The weights are suspended in the air, then released. Weight 1 has mass 9.4 kg , and Weight 2 has mass 5.6 kg.
A) How much work is done by gravity in moving each weight when Weight 1 has descended 0.40 mm?
Enter your answers in joules separated by a comma.
B) How much work is done by the rope on each weight?
Express your answers in terms of T separated by a comma.
C) Either by finding the acceleration or by finding the total work done on the system, find the speed of Weight 1 when it has fallen by 0.40 mm .
Enter the speed in meters per second.
