Help Physics Question!!!!!!!?
In the diagram provided, three ballot boxes are connected by cords, one of which passes over a pulley that has negligible friction at its axle and negligible mass. The masses of the boxes are as follows: mA = 34 kg, mB = 41 kg, and mC = 12 kg. When the system is released from rest, I have two questions: (a) What is the tension in the cord connecting boxes B and C? (b) How far does box A move in the first 0.250 seconds, assuming it does not reach the pulley?

The net force on the system is 519.4 Newtons.
(41 + 12) * 9.8 = 519.4
The system accelerates at a rate of 5.970 m/s/s.
519.4 / (34 + 41 + 12) = 5.970
a) The tension in the cord connecting boxes B and C is 45.959 Newtons.
12 * (9.8 - 5.970) = 45.959
b) Box A moves a distance of 0.187 meters in the first 0.250 seconds.
0.250^2 * 5.970 / 2 = 0.187
