In the system of the figure, we have: F- (50 + X.) Kp; M; = 20 Kg; Mạ = 20 Kg; M, - 60 Kg Find the value of the Tensions T and T1, knowing that the system moves (195 + X.) cm in a time of two seconds.

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
