(6) Three blocks of concrete are connected by a string and pulled across a frictionless table with a force T3, which has a magnitude 64.9 N. The masses of the blocks are m1=10.4 kg, TI T2 m; T3 m2 m2=22.5 kg, and m3=30.3 kg. (6a) Calculate the acceleration of the blocks as a system. Submit Answer Tries 0/10 (6b) What is the magnitude of the tension T1 (which is located between m, and m2)? Submit Answer Tries 0/10 (6c) What is the magnitude of the tension T2 (which is located between my and m3)
