Question: a=F/m; Ffriction = N; W=mg rope and Three carts with masses m=200 kg, m2 = 300 kg and m3= 100 kg are connected by

a=F/m; Ffriction = N; W=mg rope and Three carts with masses m=200

a=F/m; Ffriction = N; W=mg rope and Three carts with masses m=200 kg, m2 = 300 kg and m3= 100 kg are connected by the are pulled with the applied foree of Fa-2000 N. All three cars are experiencing friction with coefficient of friction u=0.1 Find: 1. Acceleration of the second cart. a = F M 200 2000 N-(2000) 300kg 1800N 300kg 14.0m/s 5 2. Tension in the rope, connecting first and second carts T12 Tiz 3. Tension in the rope, connecting second and third carts T23 W = 200 (9.8) = 1960 W-300(9.8)-2940 W = 100 (9.8)=980 W33
