Three sleds are being pulled horizontally on frictionless horizontal
ice using horizontal ropes. The pull is of magnitude 190 N.
Find (a) the acceleration of the system and (b) the tension in ropes A and B.
Step 1we have,a. F=maa=F/mm=m1+m2+m3=30+20+10 kgm=60kga=F/m=(190/60 )m/s2=3.16 m/s2Step 2b. ... See the full answer
