Three monkeys A,B,C with masses of 10,15,8 kg respec are climbing up and down the rope suspended from D.At the instant represented,A is descending the rope with an acceleration of 2m/s^2 and C is pulling himself up with an acceleration of 1.5m/s^2. Monkeys B is climbing up with a constant speed of 0.8m/s .Treat the rope and monkeys as a complete system and calculate the tension T in the rope at D.

Answer:
The force diagram for all three monkeys are shown in figure.
for monkey-C, we have
for Monkey-B, we have 
for monkey-A, we have
Hence tension at D = 315.4 N
